A major trend in the analytical chemistry field today is to significantly reduce the size of analytical instrument components and products. Reduction in size generally allows greater mobility, simpler operation, lower cost, and greater productivity. These characteristics are especially important in the petroleum and petrochemical industries because of the broad-ranging needs for timely chemical measurements in some of the most diverse locations. Taking the instrument to the sample instead of the sample to an instrument that is permanently located in a laboratory makes much more sense in these industries compared to many others. Liquid chromatography (LC) has been slow to embrace compactness and portability compared to spectrophotometry and gas chromatography (GC), for example. Today, new developments in materials and hardware components have accelerated efforts to develop compact LC. In the last few years, truly portable gradient LC has become commercially available, offering small high-pressure pumping systems that can deliver microliter to nanoliter/min mobile phase flow rates, fittings and transfer lines that minimize dead volumes to preserve chromatographic performance, and multiple detector options including single wavelength on-column UV-absorption detection with LED light sources, multi-wavelength diode array detection (DAD), fluorescence detection and, of course, mass spectrometry (MS). Small diameter (< 0.3 mm i.d.) packed capillary columns can be pre-mounted in temperature-controlled, easy-to-connect cartridges that literally take less than a few minutes to install/exchange. Examples of applications that are particularly well suited for compact LC in the petroleum and petrochemical industries include point detection of hazardous chemicals in emissions and effluents, chemical process monitoring and optimization, purity assessment of reclaimed process water, determination of final compositions of petroleum products, measurement of additive levels in petroleum-derived fuels, and detection of fuel marker compounds. The extremely low mobile phase flow rates characteristic of portable/compact capillary LC minimize the cost and bother of purchasing and disposing of mobile phase solvents, and clearly position the technique in the elite class of “green analytical chemistry.”

Part 1: How a Quality Management System Improves Data Quality and Laboratory Performance Since its inception, individuals active in the US National Environmental Laboratory Accreditation Program (NELAP) have struggled to try and find information to convince others that implementing a Quality Management System (QMS) according to the requirements in the TNI Standard Management and Technical Requirements for Laboratories Performing Environmental Measurements improves data quality. Over the years, various surveys and studies have been conducted to try and prove this assertion. However, the problem has been, and always will be, we never know the true concentration of a contaminant in a sample. All measurements are only estimates of the true concentration, and quality control data does not always directly correlate with the measurement of the actual contaminant. In 2019, TNI’s Advocacy Committee initiated a new effort to document improved laboratory performance and trust in the data provided by accredited laboratories. This presentation will summarize the outcomes from the Committee’s efforts and provide real examples of why implementing a QMS based the TNI standard makes a real difference in both data quality and laboratory performance.
Part 2: Evaluating the Goodness of Instrument Calibration for Chromatography Procedures Instrument calibrations in analysis methods using gas chromatography (GC) or liquid chromatography (LC) are usually created using either average response factor (RF) or linear (sometimes quadratic) regression equations. The quality, or “goodness,” of an Average RF calibration is measured by relative standard deviation (RSD) whereas the linear regression has historically been measured by correlation coefficient (r) or coefficient of determination (r2). This presentation will demonstrate that the goodness of a calibration measured by RSD is quite different than r/r2 and that while one is suitable as a calibration measure, the other is not. Relative standard error (RSE) is a way of extending the use of relative measures of calibration quality beyond the average RF calibration type.

The increasing world population and the expanding world economy have precipitated a rush to find new sources of energy for developing new oil and gas sources. Exploration today often relies upon the geochemistry of the source rock from the play of interest. The importance of Rock Evaluation Pyrolysis and the presence of specific compounds or groups of compounds in source rock is of immense importance to industries engaged in assessing the potential of a given play. Although many laboratories continue to solvent extract the sample prior to analysis, others have found that thermal extraction of the source rock will often yield a faster more accurate determination of the organic content. In this presentation, the comprehensive evaluation of Source Rock was performed using micro-furnace Pyrolysis-GC/MS with eliminating the need for conventional sample preparation.

Much effort has been applied to put process spectrometers to work for a specified application:
- Selecting instrument settings for best performance;
- Automating method development for wavelength selection and preprocessing; and
- Automating calibration updates.
At this point, there is only one task that remains for us to close the loop and completely automate the lifecycle of a Raman analyzer for any given purpose. We need to identify when a calibration requires attention and then have a system in place to institute an adjustment without supervision. Introducing a process Raman should be no more difficult to manage than installing a temperature sensor.

ICP and ICPMS gravimetric sample preparation often requires the most skilled analysts performing high precision dilutions by weight, often in a hood, for hours on a daily basis. Elemental Scientific has developed an automated technology that dilutes samples accurately and precisely. This highly flexible system prepares a variety of samples over a wide viscosity range. Combined with a second technology that incorporates non-mechanical gas infusion homogenization, automated crude oil gravimetric sample preparation is now possible.

The world is experiencing yet another helium supply crisis. ASTM International recognized this fact several years ago and requires that analytical methods up for renewal be tested using alternative gases by their ILS process so the alternative gases may be to be certified for use with the method. D2887B is the accelerated procedure method for this important simulated distillation method. This accelerated procedure has been utilized for several years using helium carrier gas. Recently, an ILS was performed to certify hydrogen and nitrogen carrier gas together with helium to be acceptable carrier gases. Data will be presented and discussed using a Thermo Scientific Trace GC to demonstrate compliance to D2887B for the three carrier gases.

D5769 for Benzene, Toluene and Total Aromatics in Finished Gasoline by Gas Chromatography/Mass Spectrometry is the ‘gold’ standard method required for certification of gasoline in many countries and regions of the world. The method challenges detection limits as well as linear ranges of the components of interest in GCMS. Also, as changes in the composition of gasoline continue to evolve, this further challenges the GCMS instrumentation to comply with the method. The new Thermo Scientific ISQ7610 MS together with the new 1610 GC provides a fresh approach to overcoming these challenges. The new Extended Dynamic Range Electron Multiplier used in the ISQ7610 provides the range necessary for the method without compromising any required MS hardware or operational parameters. Data will be presented and discussed demonstrating full compliance to the method using the Thermo Scientific GCMS. All aspects of the method specifications including sensitivity, resolution, ion check tests, calibration, and reference material compliance tests will be presented. In addition, the analysis of an ASTM D5769 ILS sample will be presented demonstrating excellent results.

The financial health and wellbeing of Midstream Oil & Gas companies relies on minimizing cost and operational expenses without sacrificing quality or system reliability. Limitations in analytical technology have prevented Midstream operators from fully unlocking their potential in cost reduction, until now. By utilizing MarqMetrix’s revolutionary Raman spectroscopy, Midstream operators now can make crucial, data-driven decisions in real time to minimize costs and drive profitability. This paper will outline the new capabilities brought to the Midstream market segment by the MarqMetrix All in One Raman analyzer by using innovative optics and chemometric modeling. The paper will also provide guidance through three unique case studies: transmix reduction of refined fuels, LPG product blending, and terminal loading operations. In all three cases, one will see that the speed of response and ability to perform quick, accurate measurement allows an operator to unleash the full potential of their operations. By utilizing MarqMetrix’s novel Raman analyzer, a Midstream operator can decrease cost, boost profit, and maintain the same level of quality and reliability that the industry demands.

The analysis of plastic has gained increased attention in recent years, due to the global push to move to a circular economy and use more recycled plastics, which require more rigorous quality control to ensure they will not produce harmful or odorous emissions.
However, there are several limitations with the existing methods for the detection of odours from plastics – such as, human sensory panels, eNose and GC-MS.
Here, we show how TD–GC×GC–TOF MS can address these challenges, by providing high sensitivity and improved separation of the odour profiles, prior to confident identification of the individual analytes.

Recent Developments and Validation of a more accurate tool for Fuel Clarity by D8148 Spectroscopic method for Haze in Fuels Providing fuel with the necessary cleanliness has been desirable since the earliest days of motorized transportation. Engine manufacturers expend significant effort to protect sensitive components of modern high pressure fuel systems from fuel contaminants. With an unprecedented number of new fuel types and feedstocks entering the worlds fuel supply, the industry is becoming increasingly concerned about fuel cleanliness and clarity. Over the decades, engine manufacturers, fuel producers and fuel distributors, worked within ASTM to establish specification limits for fuel haziness and clarity. Because of the variability and subjectivity found with the current visible methods such as D4176 and because ASTM specifications may be applied anywhere within the fuel distribution systems, fuel pipelines and transport companies have traditionally not supported these efforts. During the last five years, major pipelines have worked closely to support the optics-based technology found in D8148. ASTM D8148 Haze Clarity index is an instrumental objective technique which eliminates the subjectivity of the visual haze methods. D8148 measures and reports haze results in two formats 1) Instrumental Haze Rating (IHR) ranging from 1-6 which is calibrated to be equivalent to the D4176 Visual Haze rating, and 2) Haze Clarity Index (HCI) ranging from 50-100. HCI provides greater resolution and specificity of fuel cleanliness. With the large amount of data provided in the recent D8148 Interlaboratory Study, as well as CRC report 675, which compares D8148 to D4176 and actual amounts of water in fuel samples, it may be the time to seriously reconsider putting measurable limits around fuel cleanliness. This presentation will review the D8148 method, recent ILS results along with the data and conclusions presented in CRC report number 675.

The use of Raman spectroscopy for analysis of the various refinery products has increased dramatically in the last 20 years. While ASTM Laboratory tests are still needed and are the gold standard in order to build such models, the need to constantly run them is less. This advantage can be expanded to the online monitoring of products such as Naphtha where this fraction is a key component of the gasoline blending process and/or feed of other units within the refinery. Naphtha can be consistently separated into two fractions, light and heavy. Ranging from C5/C7 for the light cut and up to C9 for heavy. Regardless of the Naphtha process, Raman spectroscopy can be an important tool to verify the unit targets and provide tight control off key properties. It is also used extensively for distillates such as Jet and Diesel. Throughout this presentation examples will be shown of the analysis Raman can be implemented for, with the aid of regression and classification type models along with corresponding laboratory test data. Examples of the instrumentation used in refinery settings along with feedback from active users will also be provided. Raman has allowed unit operators to monitor and control their blends more effectively without having to invest in multiple individual property analyzers.

Industrial processes have common needs: reliable, accurate, and timely methods for analyzing process chemistry. Continuous monitoring with on-line liquid chromatography (LC) lets you detect process variations earlier than laboratory-based measurement and long before yield is impacted or costly process shutdowns become necessary. By improving process monitoring capabilities, you can fine-tune the process chemistry to maximize efficiency and reduce operating costs. Thermo Scientific™ Dionex™ Integral™ systems provide cost-effective, flexible solutions to apply on-line ion chromatography (IC) or high performance liquid chromatography (HPLC) to applications in a controlled setting, such as a laboratory or in a more challenging industrial environment. System modularity allows for the addition of modules and enclosures to tailor a configuration to meet specific needs. Several examples of how such systems have been applied to monitor waste and process streams will be presented.

Trace and ultra-trace analyses of elemental constituents and contaminants in environmental and industrial samples led to the demand for sensitive multi-element techniques such as ICP-OES and ICP-MS. Innovations in instrumentation enhanced robustness, performance, and productivity. However, achieving accurate results remains a challenge, especially for complex samples containing suspended and dissolved solids, organic compounds, salts, etc. Systematic errors during preparations, physical interferences from matrix components, and spectral interferences contribute to the challenges.
In this presentation, recommended best practices for the elemental analysis workflow from sample preparation to analysis will be discussed. Learn how streamlining processes within the workflow save time, resources, and help to achieve accurate results and quality data.

Classical stable gas isotopes, such as δD, δ13C, and δ18O, are well-established and valuable tools in various fields of earth sciences. They aid in constraining genetic mechanisms, provenance, transport processes, and formation temperatures. Their geothermometric usability is however limited as they lack an absolute temperature dependency. Clumped isotope geochemistry overcomes this limitation since the equilibrium distribution (‘clumping’) of heavy isotopes within multiply substituted molecules is solely dependent on the formation temperature.
The most investigated clumped isotope systems are clumping in CO2 and in CH4. It has been demonstrated that the associated thermometry delivers highly precise carbonate and methane formation temperatures. When two clumped isotopologues of one species are analyzed, it is even possible to pin down kinetic biases in cases where a sample is deviating from the expected thermodynamic equilibrium. Apart from geothermometry and the identification of kinetic processes, the addition of clumped isotope signatures to the classical stable isotope geochemist’s toolbox enables a refined forensic source apportionment of natural samples.
In this presentation we will illustrate the analytical setup (IRMS and HR-IRMS) to perform the above-mentioned measurements, and we will focus on how clumped isotopes add fresh insights into petroleum research. Besides CO2 and CH4, we will also give a perspective on the potential of clumped isotope analyses in N2, and H2, as typical compounds in natural gas reservoirs.

X-ray Fluorescence (XRF) is an immensely powerful analytical technique for inorganic elemental analysis and is widely used in industry for different quantitative analysis needs including catalyst supports, promoters, polymer additives. Different categories of XRF instruments include high-end wavelength dispersive (WD) floor models to simple but rugged energy dispersive (ED) bench-top units. With recent advances in instrumentation and affordability, it is now possible to implement robust, accurate and precise EDXRF quantification methods in manufacturing laboratories that would traditionally require use of WD instruments available at a R&D lab only allowing on-site data acquisition for process control. It is also possible to use simple ED units to extract location-specific elemental distribution using benchtop Micro XRF instruments. Aside from instrumentation, sample preparation is critical for achieving high quality XRF data and accurate quantification. This workshop would be focused on highlighting different XRF technologies and sample preparation tools, highlighting practical examples of solving real life challenges.

Most simple viscometers provide information at a single point whereas rheometers examine behaviors of the fluid over a range of points producing a flow curve. Rheological measurements are by definition far more complex than kinematic or rotational viscometer measurements because they evaluate flow properties such as shear thinning, shear thickening, viscoelasticity, and even structural recovery. When we evaluate properties of this nature, even one’s technique will affect results.
This presentation will take a closer look at how varying techniques affect rheological measurements.

It has been the author’s experience, over many years, that the automated process of lighting an FID is often unsuccessful. In this situation, it is necessary to invoke a process affectionately known by the author as “Puff the Magic Dragon” to get the detector to ignite. FIDIG solves this problem. A simple modification to an FID chimney results in consistent repeatable FID ignition. Implementing FIDIG means that an FID will ignite without external assistance. It also means the detector can be turned off when not in use and save significant amounts of air, hydrogen and make-up gas.

Unsatisfactory repeatability and reproducibility of bromine number by ASTM D1159 and bromine index D2710 prompted the investigation of an alternate method that would deliver more precise and accurate results. The precision of a classical titration is due to being able to determine the equivalence point exactly. However, bromine number is not an equivalence point titration. It is instead a titration to a diminished rate of bromine uptake. Measuring this rate is dependent on the voltametric or amperometric detection of the apparatus, on the rate of delivery of titrant, the geometry of the detecting electrodes, and on the reactivity of the sample to free bromine. Finding the bromine number reliably is a challenge in one lab with one instrument, but getting uniform results with various manufacturer's instruments in different labs has been difficult. Therefor we propose a method where the bromine reagent is added at one time in excess, allowed to react with the olefin, and the remaining bromine titrated using a classical redox equivalence endpoint. A blank of the same amount of bromine is compared to the remaining bromine to give the bromine number. The endpoint is a standard equivalence redox inflection which should be reliably detected no matter which lab or which manufacturer's instrument is used. We present results with a variety of hydrocarbon samples and standards by the classical D1159 compared to the back titration method. A discussion will follow, with plans for an ILS at the next ASTM D02 meeting in December. Potential participants are invited to attend.

Newly developed Optically Enhanced FTIR (OE-FTIR) technologies are lowering system sensitivities to levels never previously achieved by FTIR, parts-per-trillion measurements for certain applications. With the added sensitivity, detection limits for many applications are no longer dependent on the detector noise, but rather the spectral interferences. New technologies are also being deployed to eliminate or reduce this “spectral interference noise” by collecting pseudo-calibration data during sample data collection. The OE-FTIR and the spectral interference removal technology, along with process and environmental applications, will be presented.

The measurement of Ethylene Oxide (EO) from stationary sources has recently gained significant interest due to new proposed emission and exposure standards. To measure any gas at ppb levels in real-time requires ultra-sensitive instrumentation and insensitivity to cross-interferences present in the sample matrix. Sample transport can also be a challenge at these levels, and adequate QA/QC must be performed to demonstrate that the technology is producing accurate and defensible results. All these challenges will be discussed and how they are handled within FTIR-based continuous emissions monitoring (CEM) systems.

Mid-infrared FTIR gas analyzers have the unique ability to monitor many compounds over a wide dynamic range, which allows for the simultaneous measurement of % to trace level impurities without physical separation. Historically, these FTIR gas analyzers were only capable of measuring in the mid-ppb range. However, new advances in FTIR gas analysis now allow for impurity measurements at single digit ppb levels, which rivals the sensitivity of GC-based techniques, but with faster analysis times and lower cost of ownership. This presentation will discuss new hardware advances along with data demonstrating the measurement of impurities in bulk ethylene and propylene.

Infrared (IR) spectroscopy is a quick, reliable, non-destructive technique that takes advantage of molecular vibrations to identify and study chemicals. Fourier Transform Infrared (FTIR) spectroscopy is the main method in executing IR spectroscopy. With IR spectroscopy a user can identify compounds, functional groups in organic molecules, interaction between a molecule and its local environment, and perform quantitative analysis such as concentration measurements just to name a few. There are several techniques in FTIR spectroscopy such as drifts, attenuated total reflectance and transmission. This presentation will cover the theory of FTIR spectroscopy along with the different sampling techniques and their applications.

Implementation of Fourier Transform Near Infrared Spectroscopy (FT-NIR) can be used to successfully replace the need for costly chemical titration methods in the lab, while also improving repeatability of compositional measurements in a sample. FT-NIR is widely used in analyzing solid and liquid samples to characterize the quality and quantity of various components of the sample. At line and in-line applications allow for taking lab analysis directly to the sampling point in production, reducing sample timing and improving manufacturing efficiency. Real-time data analytics and robust chemometrics yield greater insight into sample characteristics and allow for continuous monitoring for any changes in the manufacturing process. This talk will cover the fundamentals of FT-NIR technology, highlight some common applications of taking the technology from lab to line, as well as how to successfully apply chemometrics to obtain the most information from your samples.

HORIBA has developed a new Process Laser Gas Analyzer (PLGA) using a unique technology called IRLAM with Quantum Cascade laser (QCL) as the light source. The QCL’s and IRLAM algorithms are optimized for each application. The analyzer houses up to six lasers in one enclosure for dedicated application. For Ethylene production it exhibits high sensitivity for Acetylene (C2H2), Carbon Monoxide (CO) and Carbon Dioxide (CO2) measurements. Field trials were conducted over six months to determine the performance of the analyzer when compared with general QCL analyzer and gas chromatographs (GC) measuring the same hydrocarbon. The analyzer achieved high stability performance for each laser and was able to rapid detect any upset condition. The PLGA-1000, with IRLAM, performs this critical C2H2 measurement both at the C2 Splitter and the Acetylene converter locations.

Paraphrasing Peter Drucker’s famous quote, there is a difference between doing things right and doing the right things. The first refers to leadership, the second refers to management. When it comes to quality control, there is a tendency to strive for continuous improvement, the idea being if problems are addressed one at a time, the overall quality will improve. But getting rid of what does not work does not necessarily produce the desired results. So, the question is; Are we doing things right or are we doing the right things?
This presentation will propose a Statistical Quality Control approach that looks at the analytical laboratory as a whole system rather than individual parts and how to refine the system to achieve the desired quality improvements. The performance of a system depends on how the parts fit, not how they perform separately. We have plenty of knowledge, let’s increase our wisdom. Let’s explore quality and continue our journey from efficiency to value.

SCD’s are the “go to” for sulfur speciation since the mid 1990’s. Other sulfur detectors preceded them for sulfur speciation but had their own challenges. SCD’s address these challenges with superior linearity, equimolarity and detection limit with minimal matrix interferences. Because of SCD’s benefits, there are now three vendors with their own SCD on the market.
Lummus Technology has all three vendor SCD’s and 4 different models. This presentation will focus of comparing these four detectors, with the same sample sets and assess which one is more reliable, more stable and has better stability, including an insight of the reason these detectors behave as presented.

Optical gas imaging (OGI) cameras have been used by a variety of industries for many years since the inception of the technology in 2005. Most notably in the oil and gas industry for the detection of hydrocarbon gases. More recently, the petrochemical industry has looked to adopt new technologies like OGI for effective leak detection of hydrofluorocarbon gases. Historically, leak detection was performed with either handheld instruments, like a toxic vapor analyzer, or fixed ambient air monitoring solution where a technician would be deployed to find a leak source after an alarm. Optical gas imaging cameras allow operators to streamline the leak detection and repair (LDAR) process by finding leaking sources faster and from greater distances than before, increasing operational safety.

SIFT-MS is a real-time field-deployable mass spectrometer that provides online trace analysis of ambient air with detection limits down to sub-ppbv levels. SIFT-MS has some key characteristics that make it ideally suited to industrial fence-line monitoring applications:
-SIFT-MS can be installed at the fenceline for direct point-source air quality measurements providing a 24/7 data stream with automated instrument validation with minimal periodic operator intervention.
-SIFT-MS provides highly sensitive monitoring of a diverse range of species through the utilization of both positive and negative chemical ionization agents. Target compounds include: acid gases (incl. HCl, HF), permanent gases (incl. CO2, SOx, NOx, Ozone), volatile organometallics, oxygenates (incl. aldehydes; formaldehyde), nitrogen-containing compounds (incl. amines; ammonia), reduced sulfur compounds (incl. hydrogen sulfide), halogenated compounds, and hydrocarbons.
-In addition to the mass spectral identification of species, SIFT-MS provides an additional dimension of chemical selectivity through the simultaneous application of multiple reagent ions. This vastly reduces the number of false-positive reports compared with online mass spectrometers that rely on a single ionization mechanism.
Several case studies will be presented, including the deployment of SIFT-MS for 24/7 continuous monitoring at fixed installations and mobile measurements at the fenceline of a Korean semiconductor manufacturing facility (Samsung Electronics), and the localization of fugitive emissions at a gas refinery in New Zealand. Highlights from the Syft Clean Air Roadshow in 2021 will also be discussed.

Removal of oil and grease from wastewater is imperative as it can negatively affect human health and drastically reduce the diameter of sewage pipes, restricting flow of wastewater and causing backups. Due to the nature of some samples potentially exceeding the limit of 1000 mg/L of oil and grease, US EPA Method 1664B has allowed for the reduction of sample volumes for gravimetric analysis. With this study, labs are no longer bottlenecked with samples that are heavily laden with oil and grease and are challenging to extract. The reduction of sample volumes in turn reduces the amount of oil and grease that needs to be filtered out from any given water sample that was originally one liter in volume, decreasing the sample loading time and increasing sample throughput. The extraction process is further streamlined using two different types of automated extraction systems. The data from 250 mL sample extractions demonstrates that the recovery of oil and grease on each extraction system, is within the necessary recovery range outlined in US EPA Method 1664B, remaining compliant with the quality and consistency requirements. The difficulty of extracting 100 mL samples will also be discussed.

In today’s environmental laboratories there are many methods and techniques being used in sample preparation. One technique-driven method that has been described as a bottleneck is the fractionation of Extractable Petroleum Hydrocarbons (EPH) in water and soil extracts. This method recommends using 5g, 20 mL silica gel cartridges to separate the aliphatic and aromatic compounds from the sample extract to be analyzed by GC-FID.
As laboratory challenges grow with increased samples loads, turnover of personnel while taking in highly concentrated water and soil matrices for extraction, it can be challenging to streamline the fractionation workflow. With such hurdles it often results in having to refractionate the sample and or entire batch, creating a bottleneck in sample throughput.
This work will demonstrate the advantages and disadvantages of EPH cartridges in multiple formats and fractionation platforms. This work will highlight how the workflows can help laboratories overcome this bottleneck with consistency and quality by utilizing batch type processing with automation while demonstrating how cross-contamination is eliminated.

High Temperature Simulated Distillation has one of the most challenging matrices with compounds from C4 (or below) to asphaltenes. The entire sample is injected on column, and the GC oven programs from -20 oC to 425 oC. These create wear on the column. Adaptations to the GC and column technology have evolved.
This presentation will discuss the adaptation used, how they are beneficial, and tricks that can be applied to keep the system “up and running” with repeatable results.
ASTM Method D7900 will also be examined. D7900 gives a more accurate determination of C1 to C9 portion of the crude analysis. When merged with D7169, gives a more accurate boiling point distribution.

Iron-containing compounds can be problematic during the refinery of petrochemicals or the manufacture of semiconductor devices. These Iron compounds, including particles, can lead to corrosion of refinery equipment, adversely affecting the petroleum value chain. In the semiconductor industry, Fe Nanoparticles (NPs) can lead to cone defects on the surface of wafers, which cause shorting of electrical signals. Single particle inductively coupled plasma mass spectrometry (spICP-MS) is increasingly used to study NPs. Currently, most studies have focused on NPs in aqueous sample matrices, with few studies on nonaqueous matrices. One of the issues for this is the lack of hydrocarbon matrices, and solvent-compatible reference nanomaterials (RMs) to validate new methods. Two gold (Au) polystyrene-coated NP RMs in toluene and silica-shelled iron oxide (Fe3O4) alkylsilane-modified NPs in o-xylene were synthesized. spICP-MS and transmission electron microscopy (TEM) were integral to developing and characterizing the standard materials.
In this talk, we will share the spICP-MS method on the Agilent 7900 ICP-MS used to characterize the synthesized Au and Fe NP RMs. NIST crude oil standard reference material (SRM) and a NIST residual fuel oil SRM were also measured for the natural Fe NP content and spiked Fe NP content.

Excimer UV Fluorescence (EUVF) is a relatively new technology that has demonstrated an unsurpassed linear dynamic range than that achievable with conventional UV Fluorescence analyzers. This has allowed it to successfully meet the sulfur measurement and calibration requirements of regulatory standard US EPA 40 CFR Part 60.18 Subpart Ja, using a single valve and calibration standard over the entire measurement range. EUVF has also demonstrated excellent sensitivity making it ideal for accurate, low-level measurement of sulfur in fuels, to meet required reductions in global emissions. Standards such as the American Tier III, European Euro 6, and the Indian Bharat VI set quantitative limits on permissible amounts of specific pollutants that can be released during combustion where the emission of oxides for both Sulfur and Nitrogen are regulated. Data will be presented showing successful compliance to repeatability requirements within limits set by these standards. EUVF has also been shown to exhibit unsurpassed nitrogen interference, making it the choice for precise measurement of low sulfur levels required by these regulations, particularly when high nitrogen content is present. EUVF is now a proven technology with ATOM Instrument, part of Process Insights, being the only manufactured brand incorporating this superior version of UV fluorescence in their analyzers.

When analyzing samples with diverse and variable composition for nitrate and nitrite together with some of the other targets from these methods (e.g., F-, Cl-, Br-, PO4-, and SO4- from EPA 300), laboratories may run into challenges. For example, high concentrations of chloride in the matrix can mask the presence of nitrite, preventing the detection of the later by suppressed conductivity detector required in the method. Hence, two or more injections may be needed for obtaining the required results, resulting in decreased productivity. In this work, we first optimized the method conditions to maximize lab productivity and turn-around-time for the analysis of the seven anions targeted in EPA 300 in a run-to-run time of 4.5 minutes (4.0-minute gradient). In an attempt to further increase the efficacy of the method, we evaluated two approaches to eliminate the need for sample-reruns when results from various anions are outside the calibration range or interferences are present: 1) lowering the injection volume (down to 0.2 µL) to avoid the need for sample dilutions (in- or off-line) and 2) using a conductivity and UV detectors in-line to detect nitrite in the presence of high concentration of chloride. In this presentation we will present the results from the method performance evaluation including but not limited to linearity, sensitivity, and reproducibility.

Microplastics, defined as those in size <5mm, are becoming more abundant in marine waters due to the continuous discharge and their resistance to environmental degradation, and they are harmful to the organisms and ecosystems in environments. It is, therefore, critical to understand how plastics degrade biologically and photochemically, and how contaminants, such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), are sorbed to microplastics. In this talk, I will briefly summarize several of my recent or on-going projects related to microplastics, including nurdles pellets along Texas coasts and their associated PAHs and PCBs. Also included are results of plastic degradation from laboratory photooxidation and biological degradation in the deep sea. I will also talk about how state of the art analytical tools, including microscope FTIR, pyrolysis GC/MS and gel permeation chorography, are used to analyze plastic samples.

Quality of Jet Fuel is key to flight safety. It’s composition, in particular aromatics content, is regulated to ensure proper combustion characteristics and compatibility with aircraft fuel systems. As the aviation industry moves to lower carbon intensity, new fuel types emerge which differ in composition from traditional petroleum-based fuels. Legacy test methods struggle to meet performance characteristics required to test these sustainable aviation fuels (SAF). A new test method (ASTM D8396) was developed, based on comprehensive two-dimensional GC. This method provides detailed hydrocarbon group-type composition, whilst the simplicity of the flow-modulated setup allows implementation in routine lab environments.

Many industries monitor atmospheric conditions to measure gas pollutants in humid environments. Varying levels of ambient humidity can interfere with gas monitors and sensors and diminish response factors. Calibration of gas monitoring and detection devices should relate to ambient conditions and include the percent relative humidity (%RH) consistent with surrounding areas. Creating various %RH levels in a zero-gas stream or a calibration gas stream can be challenging and ineffective if done improperly. A permeation system that supplies accurate calibration gas with controlled %RH at varying levels is an effective solution for calibrating or exposing monitors, detectors, and sensors at ambient conditions.

Polyethylene is one of the most important industrial polymers, and NMR is essential to evaluating its molecular structure by measuring co-monomer content, sequence distribution, unsaturation, and long chain branching.1 Routine polyethylene NMR analyses require the use of specialized, deuterium-based solvents. While necessary for locking and shimming the NMR field, these solvents are expensive, subject to supply interruptions, and often hazardous. Here, we share our progress at Dow Chemical to find safer, deuterium-free solvent systems for routine polyethylene NMR.

Removing moisture concentration levels down to ppm, ppb, and ppt levels is critical in many manufacturing, electrical, and medical processes. Moisture sensors can be used to determine if an environment is optimal for the process but calibrating the sensors with accurate moisture standards can be daunting. Water moves from areas of higher concentration (such as the atmosphere) to areas of lower concentration (such as the moisture standard) by permeation and diffusion. It is also a polar compound that sticks to almost any surface that has a charge. Creating a Moisture Standard can be done if approached correctly.

The analysis of moisture in chemical production and solvent recovery is commonly performed by coulometric Karl Fischer titration (KFT) in an offline wet chemistry lab. The time required for measurements and manual sampling often cause a lag between receiving data and process implementation. This results in either unnecessary drying steps or insufficient drying, increasing costs. A better solution is online NIR measurement. However, NIR instruments often require significant effort to calibrate, especially at the levels required for many high-purity streams.
In this talk, we demonstrate a system that eliminates the calibration effort by automatically building and checking the calibration, without manual sampling. This capability allows moisture measurement systems to be calibrated at the factory down to approximately 5 ppm and installed in pipelines and reactors without additional calibration effort.

Monitoring corrosion is key to maintaining successful long-term operation of oil pipelines and refineries. Amines are routinely added to neutralize hydrogen sulfide vapor for transport of crude to the refinery and are typically used to strip hydrogen sulfide, carbon dioxide, and other acidic gases in the refining process. However, too much amine present in the wrong location can increase corrosion rates. Therefore, it is in the industry’s best interest to monitor these corrosion sources and work is underway at ASTM to develop a standard practice for extraction of water-soluble amines in crude oil.

Polyurethanes (PURs) are produced by reacting methylene diphenyl diisocyanate (MDI) with low MW polyols which are distributions of multiple individual diols. The PUR oligomers consist of a mixture of structural isomers at each mass in the distribution. Isomers can be studied by using monodisperse, polyols. This approach becomes intractable for larger MW polyols. We demonstrate a straightforward synthesis approach for generating PUR oligomer distributions with unique numbers of polyol attachments. Four polyols (PEG, PPG, PTHF, and PBA) were reacted with phenyl isocyanante (PhNCO) to produce distributions of PUR oligomers exhibiting unique numbers of polyol attachments. Structural characterization by Ion mobility and high resolution mass spectrometry confirmed these PUR oligomers are monodisperse and MS/MS results indicated the products follow known fragmentation mechanisms.

Progress in science and engineering relies increasingly on synthetic materials with well-defined structures, optimized to perform specific biomedical, technological, consumer, and environmental applications. Mass Spectrometry (MS) using matrix-assisted laser desorption/ionization (MALDI) and/or electrospray ionization (ESI) provides a powerful and versatile tool for the molecular characterization of such compounds as well as for imaging the molecular composition and defects of solid polymer surfaces. The dispersive nature, high mass resolution, and unparalleled sensitivity of MS permit the conclusive and confident elucidation of molecular weight (MW), functionality, and end group distributions and are particularly suitable for monitoring reactions that change the mass. This information required for both structural elucidation as well as the determination of polymerization mechanisms. Complex mixtures and multicomponent blends can be simplified with multidimensional approaches, involving in-line separation by polarity, using liquid chromatography (LC), and/or by ion size and shape, using ion mobility (IM) spectrometry. Meanwhile, large macromolecules and crosslinked networks can be made analyzable by mild thermal degradation that predictably breaks weak bonds while preserving connectivity and functionality. Conversely, mass spectrometry imaging (MSI) techniques with solvent-free MALDI can be utilized to determine the molecular composition and defects in the top molecular layer of synthetic polymer surfaces (

Water in petrochemical and refinery streams can cause problems for processors. Freezing of pipe lines and valves and also poisoning of expensive catalysts are just a few examples. Monitoring water in petroleum from an upstream source to the downstream processing plant is critical to insure uninterrupted operation. Unlike the Karl Fischer analysis, the GC water analyzer does not suffer from the adverse effects of the petroleum matrix which can skew the KF results. GC methods can bypass the undesirable chemical interference that would otherwise be present like “Sulfur interaction” and acetone. The use of the LUMA™ VUV detector and Supelco’s water analysis column “Watercol” are combined to separate and measure the water in a propane, propylene and butane streams. The VUV LUMA detector provides sensitive and accurate results using hydrogen as carrier gas. Measurements can be made down to water levels of less than 1 ppm.

Determination of hydrocarbon (HC) type distribution in petroleum fluids is generally done with data from two gas chromatographs (GC); one with a flame ionization detector (FID) and one with a mass spectrometer (MS). The resulting GC-MS data is then taken through calculations based on the Robinson whole oil method to determine hydrocarbon type composition in each fraction. The method reports four saturated hydrocarbon types, twelve aromatic HC types, three tiophenic and six unidentified aromatic groups and does not require a prior separation of a sample into saturates and aromatics fractions. Moreover, the above method was applied to provide the distribution of individual HC types in function of carbon atom number defined by Simulated Distillation (SimDis) in the region of interest.
The challenge was to get a hydrocarbon breakdown on volatiles in air to attain a flux rate. Initially, the maximum concentration at steady state was determined by sampling onto two sets of thermal desorption sorbent tubes one after the other and analyzed in separate runs. The flux rate experiment was not measured in a constant state, but in a changing state. Therefore, the requirement was to sample one tube and analyze it by FID and MS detectors at the same time. To accomplish this, a microfluidic devise was employed.
The method, thermal desorption and microfluidic device developments will be discussed.
