A New PEG GC Column With Improved Inertness Reliability And Column Lifetime
Agilent Technologies, Inc.
Today's demanding GC and GC/MS applications has become more focus on sensitive and reproducible qualitative and quantitative analysis of more challenging active analytes. An inert GC flow path is therefore required to eliminate the adsorption of active compounds of interest onto active sites anywhere from injection to detection. Building on experience in developing enhanced surface deactivation chemistries, Agilent Technologies has been successful in improving the inertness of the entire GC flow path that is directly in contact with critical, active analytes that are susceptible to breakdown or otherwise inferior chromatographic detectability. In this study, we present Agilent J&W DB-Wax Ultra Inert (UI) GC column, an upgrade, UI version of the Agilent DB-Wax column, where inertness performance extends to a new state of the art in capillary gas chromatography (1). DB-Wax UI was evaluated via a rigorous inertness testing procedure using some of the most active probes for today's demanding applications. Overall superior performance for inertness, thermal stability at upper temperature limits and column to column consistency on DB-Wax UI ensures the most sensitive and reproducible analytical results for active analytes. Furthermore, the same selectivity as the Agilent J&W DB-Wax which have been commonly used for over 35 years for analysis of a wide variety of compounds in numerous applications facilitates as simplified upgrade to the enhanced, UI version with minimal revalidation.

A Solution for Determination of High-Concentration Aromatic Compounds in Finished Gasolines Satisfying ASTM D5769 using a New Benchtop GC-TOFMS
A new benchtop time-of-flight mass spectrometer demonstrates results that exceed expectations for ASTM D5769 for determination of total aromatics in finished gasolines by GC-MS. A common difficulty encountered with this method is the concern with saturation of the ion source, which leads to nonlinearity in calibration curves, especially for the quantification of the high-concentration aromatics, such as toluene. Linear calibration curves were built for the standard method analytes and then applied to samples with the addition of semi-quantification for similar analytes on a sample of 93-octane gasoline, satisfying all method requirements.

Acid Number of Crude Oils and Petroleum Products by Catalytic Thermometric Titration using ASTM D8045
ASTM Standard D8045 describes the analysis of acidity in difficult crude oils and petroleum products using thermometric titration. This new technique overcomes solubility and precision challenges encountered with traditional potentiometric measurements. Thermometric titration is more precise, faster and reduces solvent requirements. Through eight years of development work in ASTM and thousands of sample measurements this new standard is shown to be rugged, robust and transportable across many labs and technicians. This poster provides a clear analysis of data acquired with this new method and details the benefits of thermometric titration for safer and more precise acidity analysis.

Analyses of Trace Elements in Fuels with ICP-OES
Thermo Fisher Scientific
The presence of trace elements in fuels like gasoline and kerosene can lead to a number of detrimental effects both on the engine using the fuel as well as the environment.
The analysis of trace elements is therefore essential to ensure that performance of the engine is not affected by the fuel and that environmental damage does not occur when trace elements are transported from the engine to the environment via emissions. Concentrations of trace elements in gasoline and kerosene are controlled by fuel specifications which vary from country to country and are influenced by desired engine performance and environmental factors. High matrix tolerance and the advanced method development software of the Thermo Scientific ICP-OES allows for simplified analysis of challenging matrices like kerosene, gasoline and other organic solvents.

Analysis of Sulfur Compounds in Light Petroleum Liquids by Gas Chromatography and Pulsed Flame Photometric Detection(PFPD) Using ASTM Method D5623
ASTM D5623 is primarily for the determination of volatile sulfur-containing compounds in light petroleum liquids with a final boiling point of approximately 230*C or lower . Many sulfur compounds are harmful in the refining process and the ability to identify them is useful in controlling sulfur compounds in finished products. This is especially significant to compliance with the Tier 3 regulations to lower the sulfur content in gasoline making emission control systems more effective.

Battling Fuel-Washing: Identification of Accutrace S10 in Diesel Samples Using a New Benchtop GC-TOF MS System
Government-subsidized farm fuels are often dyed to distinguish them from consumer diesels. "Fuel-washing," where dye is removed from fuel that is subsequently resold at higher prices, is a major concern for many tax, regulatory, and law enforcement agencies. Without the need for any additional separation methods or sample preparation, diesel samples spiked with the newly developed fuel marker Accutrace S10 were analyzed in less-than-15-minute runs by a new benchtop time-of-flight mass spectrometer that allowed for quantitation of fuel marker from 100% subsidized fuel to less than 1% subsidized fuel, exceeding the HRMC targeted quantitation range.

Comprehensive Real-time Fenceline Monitoring Using SIFT-MS
Petrochemical facilities frequently emit volatile organic compounds (VOCs) as part of their regular operations, but occasionally the levels at the boundary exceeds regulatory levels. These emissions are transient and therefore not well characterized by traditional techniques.
Selected-ion flow tube mass spectrometry (SIFT-MS) is an analytical technique that detects and quantifies VOCs and inorganic gases directly in air to part-per-trillion concentrations within seconds. The high-speed analysis provided by SIFT-MS allows the instrument to provide continuous fenceline monitoring.
This paper presents results of real-time fenceline monitoring undertaken at the boundaries of petrochemical and other industrial facilities in New Zealand and Taiwan.

Demonstrating Porous Polymer Plot Column Polarity On Various Compound Species Using RI's
This poster will demonstrate the polarity of Restek's porous polymer plot columns using various compounds species as well as compound position values, i.e. Retention Indices relative to n alkanes eluting before and after the compound of interest. Different GC's and/or different laboratories will have a negligible effect on the RI's values, thus making compound identification and column selection faster and easier. RI's are far more accurate than attempting to identify compounds based on retention times and/or relative retention times when generated on different GC's and laboratories.

Effective Viscosity Management in Asphalt and Lubrication Oil Refineries
There are more than 700 refineries worldwide with a capacity for 82 million barrels of oil per day. A barrel of crude yields gasoline, fuel oil, jet fuel, diesel, asphalt, lubrication oil and other refined products, but actual output varies dramatically by refinery. Demand for energy continues to rise along with pressures on producers to streamline and speed production, increase yield and operate more efficiently. Viscosity is one on the most critical measures of product quality for virtually every refinery product. New developments in viscosity measurement are enabling refineries significant improvements in production quality, cost and output. This presentation will discuss the latest developments and the return on investment for the refinery.

Evaluation study of screening system for phthalate esters in polymer material using Pyrolysis-Gas Chromatography Mass Spectroscopy
Shimadzu Scientific Instruments
Starting in 2019, four phthalate esters (DIBP, DBP, BBP, DEHP) will be added as restricted substances in the RoHS directive. Because the number of samples of RoHS testing is very large, an effective way for testing these and other phthalate esters is required. We developed a phthalate screening system using pyrolysis-GC/MS (Py-GC/MS) with easy sample preparation that does not require organic solvent.
In this study comparing with the result of a conventional method (solvent extraction-GC/MS), the quantitative accuracy of phthalate ester analysis using Py-GC/MS was evaluated to confirm the applicability of phthalate screening for RoHS testing.

High Performance Chromatographic Quality Diatomaceous Earth Developed By
Restek Corporation "NOW AVAILABLE"
The use of Diatomaceous Earth solid support support media for use in packed
columns was said to be obsolete back in 1980 with the introduction of glass
capillary columns and followed soon after by fused silica capillary columns.
However, the packed column is still thriving today with use in USP, petro and
process analyzer markets. Within the last decade the quality (inertness) and
available supply of chromatographic quality DE has had limited availability. Restek
has solved the quality and availability issue by developing their own line of high
performance DE called DiatoSorb W HP. Surface area, particle size distribution,
density and pore size are all tightly controlled. The poster will high lite the quality
of the product.

Methanizer – A Simple Solution for CO/CO2 Gas Analysis by Gas Chromatography
CO, CO2 are common components in refinery feedstocks, fuel cells, greenhouse emissions, and are present in many other industrial processes. Accurate and precise determination of the final components can save industries millions of dollars per year. A modern, user friendly and accurately controlled Methanizer was developed that can be easily integrated into any existing GC/FID system. The Methanizer consists of a Ni-catalyst in a heated chamber that converts CO and/or CO2 in the presence of hydrogen, into a FID detectable gas, methane. The GC independent controller runs a PID algorithm to proportionately control the heating of the Ni-catalyst to within ±1°C, assuring controlled and reliable conversion of CO and/or CO2. CO and/or CO2 analytical solutions, robustness and system performance will be presented.

On-stream Raman spectroscopy in chemical processing
1 Kaiser Optical Systems Inc. 2 Ascend Materials
Raman spectroscopy offers a real-time non-destructive method to measure and control chemical processes. As an in-process analyzer, Raman can measure gases, liquids, turbid media or solids in ambient conditions, corrosive or reactive streams, high pressure or temperatures. New approaches to batch reactions, microreactors, flow synthesis and continuous manufacturing extend the applicability and utility of Raman spectroscopy in chemical manufacturing. Examples where the use of Raman spectroscopy has been shown to improve process efficiency, predict reaction end times, or report the presence of a polymorphic crystal form demonstrate Raman spectroscopy as a versatile technique in chemical processing from laboratory to manufacturing.

Parallel detection GC×GC-TOF MS/FID for routine petrochemical analyses
Precise characterization of petrochemical samples is crucial for quality control, and also to understand the reactions that take place during refining processes.
Parallel detection GC×GC provides targeted and non-targeted approaches in a single run. We also demonstrate Tandem Ionisation for simultaneous acquisition of both hard and soft EI spectra, providing improved speciation of isomers that are indistinguishable based on 70 eV data alone.
This approach therefore pushes the boundaries of hyphenated systems by providing three information-rich datasets per acquisition - namely robust quantitation by GC×GC-FID, untargeted screening by GC×GC-TOF MS (70 eV) and confirmatory identification by soft EI.

ProEZGC - Free, Web-Based Tool for Gas Chromatographic Modeling
Evaluating Retention Time Accuracy: Modeled vs. Actual Data
Method development in gas chromatography (GC) is time-consuming and costly. While there are established methods for analysis of petroleum samples that provide adequate separation of the entire class of targeted compounds there is generally room for improvement in resolution and overall runtime. In addition, many laboratories are searching for a conformational analysis which is rarely found in the methods. Other laboratories are interested in verifying current elution order, reverse peak identification or simply are challenged with a new sample.
The ProEZGC Chromatogram Modeler generates and optimizes modeled chromatograms using an indices database of over 5000 compounds. This is a free, web-based program that allows the user to select compounds, stationary phases, film thicknesses, temperatures, column lengths, column internal diameters and flows. This presentation will examine ASTM D6729 parameters and retention time data and compare empirical data to retention times generated by the EZGC Chromatogram Modeler. We will also examine other examples of this tool's utility in method development for other classes of compounds, for instance, hydrocarbons found in gasoline and sulfur in natural gas.

Semi-empirical VUV spectra model for PIONA compounds
In principle, one must obtain each of PIONA compounds' VUV spectrum for PIONA component analysis using GC-VUV technique. However, with the number of C increases, the number of possible structures of PIONA compounds increases dramatically, and obtaining each of these compounds' spectrum is impractical. By comparing available experimental VUV spectra and theoretically calculated spectra of PIONA compounds with low C number, we are working on building a model to generate reliable semi-empirical VUV spectra for PIONA compounds which possess high C number and lack of experimental data. We expect with the aid of these semi-empirical VUV spectra, reliable PIONA component analysis for compounds with high C number will become feasible.

Transferring interfacial rheology data from lab tests to practical midstream processing: Optimizing demulsifier performance to reduce corrosion and pipeline pressure peaks
Using the oscillating drop method, various demulsifier systems were investigated. Different concentrations of asphaltene mixtures in toluene were characterized and, it was found that the change in storage modulus (E') of the asphaltene-water interface upon addition of demulsifying agents strictly correlated with the stability of water-in-oil (w/o) emulsions. The most promising demulsifier system was identified, was tested in field for practical midstream processing, and was compared to a commercially available standard demulsifier. Interestingly, deviations in pumping pressure could be reduced from 11.5 ± 2 atm to 11.0 ± 0.5 atm after switching from the standard to the identified demulsifier system. Results show how interfacial rheology measurements on a lab scale can be transferred to petroleum midstream processing to optimize the performance of demulsifying agents.

JFTOT + OptiReader + IHT = permanent unified thermal oxidation stability test results
ASTM D3241 measures the thermal oxidation stability of jet fuel using a JFTOT test. The results are read through a subjective visual rating using VTR technology. With the advancement in technology, it is now possible to eliminate the subjectivity by the use of a metro-logical method. This has created a need for managing a higher amount of data. PAC's JFTOT, OptiReader and Intelligent Heater Tubes (IHT) combination solves this issue by allowing users to manage the increased data electronically. This powerful ecosystem eliminates the need for a paper trail by storing results permanently in a unified test report.

Catalyzed Thermometric Titration of Acid Numbers ASTM D8045
Mettler Toledo, LLC
The catalyzed thermometric titration of acid number in crude oils and petroleum products is a departure from the traditional pH electrode detected acid number. The reaction of base with acid in the sample is not exothermic enough to follow directly. By using an endothermic indicator, paraformaldehyde, the acidity can be determined. The KOH reacts first with the acid. When the acid is used up, the KOH reacts with paraformaldehyde in a strongly endothermic fashion. The titrator picks the point where the temperature begins to drop. The advantage of the method is a fast titration of around one to two minutes, and a sensor that does not depend on ionic conductivity nor need to be rehydrated. Results are repeatable and similar to what is obtained by ASTM D664. The instrument (standard titrator), reagents, and the accessories needed will be shown.

Simplify your Annual Recalibration Ritual with the new ADM Flow Meter
Maintaining a NIST-certified flow meter typically involves sending the device off-site for recalibration at least once per year. This process can waste hundreds of dollars in downtime, shipping costs, and paperwork. The ADM flow meter is a reliable platform for measuring volumetric gas flow without having to know the gas composition (limited to non-caustic gases). Moreover, the ADM flow meter does not have to be shipped back for recalibration to maintain NIST-Traceable standards. Simply replace the old cartridge with a new NIST-calibrated cartridge.

Near infrared spectroscopy has been used widely in the polymer industry. Compared to traditional methods such as wet chemistry and chromatographic methods, NIR spectroscopy provides considerable advantages in process and quality control applications through five fundamental benefits:
• low to no cost of consumables such as solvents, columns, reagents
• real time analysis - generally less than 10 seconds measurement time
• multiple components per analysis
• elimination of sample preparation time.
• elimination of many sources of systematic error
This presentation will present two FT-NIR polymers applications: one is the real time hydroxyl number and isocyanate number monitoring during a polyurethane reaction, and the other is the off-line quality control of percentage styrene in styrene copolymer. Galaxy Scientific's QuasIR 2000 fiber system and QuasIR 3000 integrating sphere system were used in this study. The methods implementation and accuracy will be discussed in detail.

Application of GC-MS and FTIR Methods for the Analysis of Volatile Organic Compounds near Fracking Facilities for Oil and Gas Production
Middle Tennessee State University
Fracking facilities are often associated with the emission of volatile organic compounds (VOCs) into the atmosphere. In order to investigate the composition of these VOCs, canisters were used to collect grab samples at multiple locations in Karnes County, Texas, where many oil and gas production facilities are in operation. The samples were analyzed using gas chromatography-mass spectrometry (GC/MS) with a cryogenic pre-concentrator and the low molecular weight pollutants including C1-C3 compounds were analyzed using Fourier Transform infrared spectrometry (FTIR) with a 10-meter gas cell. Selected samples show high levels of C3-C8 hydrocarbons as well as benzene, toluene, ethylbenzene, and xylenes.

Development of a laboratory corrosion test method to assist the pipeline transportation industry
Koehler instrument Company
Traces of moisture found in petroleum products will cause corrosion on interior surfaces, potentially damaging pipelines and causing deposits in engines. The method used for determining the corrosive properties of gasoline and distillate fuels in preparation for transport through a pipeline was developed by the National Association of Corrosion Engineers. The NACE TM0172 test method takes four hours to perform and requires 300mL of sample. While this has served the industry well for many years, there has been a strong interest from all the key stake holders for a quicker method with faster turnaround, smaller sample size, and better repeatability and reliability.
Working closely with key refineries over the last few years, and with numerous trial and error experimental setups, a quicker, easier, and more reliable method has finally been developed. This ingenious laboratory experimental technique will save the industry significant time especially at pipeline transfer stations where a quick QC turnaround is necessary to determine if the product passes the corrosivity test.
Based on this idea, a new ASTM test method ASTM D7548 for Determination of Accelerated Iron Corrosion in Petroleum Products has now been developed and an international round robin will be conducted soon. This new ASTM method uses only 50mL of sample and takes less than a fourth of the time to complete the test. This poster will discuss in detail the development of this test technique, and the authors will also discuss the reliability of the accelerated test. Finally the authors will also present results that show comparative data between the NACE test and ASTM D7548, the accelerated iron corrosion test (AICT).

The Karl Fischer titration is one of the most widely accepted methods for determining water content. While there have been improvements in reagents and instrumentation which have greatly increased the accuracy and reliability of the method, the need for calibration, validation and control, remain unchanged. Dealing with traditionally chosen pure water may present its own challenges, especially when trying to accurately deliver very small quantities.
This paper discusses the importance of sample size and its influence on standard selection. Various manufactured standards for the volumetric and coulometric analysis, along with the Karl Fischer oven, will be discussed.

The need for fuel is growing worldwide along with the industrialization of many Asian and African countries. Along with this growth is an increase in fuel theft in the form of dilution. Dilution can range from water to lower grade fuels. While water dilution can easily be determined, low grade fuel dilution requires sophisticated analyzers that determine various fuel properties. Unfortunately, such analyzers are confined to laboratories, and the measurements can take hours to perform. In an effort to meet the need for rapid verification of fuel at ports and depots, we have developed a field-portable analyzer that can determine multiple properties within 10 seconds. The portable fuel analyzer measures the near-infrared (NIR) spectrum of a fuel sample, which is correlated to the properties using multivariate statistics and a fuel sample data base consisting of previously measured NIR spectra and ASTM properties. Twenty-two correlation models have been developed for diesel, gasoline, and jet fuels that predict fuel properties comparable to ASTM reproducibility values. The analyzer accurately determined properties for 16 diesel samples previously characterized at two ASTM certification laboratories. The analyzer design, model development, and the sample measurements are described. This innovative analyzer will certainly be a useful tool and save immense time and money for all parties interested in quick and inexpensive accurate onsite fuel verification.
