Streamlining Spectroscopic Calibration
The adage “you can’t control what you don’t measure” may be old but it will always hold true. In the hydrocarbon processing industry, optical spectrometers are deployed to measure the chemistry and the physical attributes of the products we produce. Spectroscopy’s advantage is that it is non-destructive, fast, can be run on-line, and provides quantitative information. On a continuous basis, a maintenance effort is required to determine the optimum number of factors and identify outliers that degrade model performance. This updating can be completely automated and optimized for any spectrometer employing any software.

Gas Chromatography: Beginner to Expert in 4 hours!
- Axion Analytical Labs and Training Institute, Inc.
Gas Chromatography is one of the most popular analytical tools in the world, yet very few people understand how it works. During this 1-day course, you will not only understand it, but you will master it! We'll start by reviewing the fundamentals of GC (column flow, temperature, length, diameter, film thickness, stationary phase, split ratio, etc.). Then I'll show you how to use those fundamentals to develop and optimize methods from scratch. It is like driving a car: Once you understand the purpose of the pedals and steering wheel, you can drive anywhere you want without thinking about it. By the end of this class, you will be able to develop a method from scratch, optimize that method, cut the analysis time in half for any current method, and troubleshoot/fix your instruments. My goal is to put you into the driver's seat, so you are in control of your GC and not vice versa! Dr. Polite has made a 25-year career out of explaining complex topics in an easily understood manner. This class is no exception.

Advancements in EPH Fractionation: Overcoming Challenges and Enhancing Efficiency
Extractable petroleum hydrocarbon (EPH) fractionation is a specialized methodology utilized to separate aliphatic and aromatic fractions of petroleum hydrocarbons found in environmental samples. Information obtained from EPH fractionation testing provides a more detailed assessment of the hydrocarbon composition and helps environmental scientists identify the potential impact of these contaminants. The three laboratory techniques commonly used for Extractable Petroleum Hydrocarbon (EPH) fractionation are High-Performance Liquid Chromatography (HPLC) Fractionation, Solid Phase Extraction (SPE), and Gas Chromatography with a secondary column (GCxGC). Each technique has challenges such as low sample throughput, high solvent usage, breakthrough of fractions, potential contamination, and issues related to analytical data processing. This investigation outlines challenges for solid phase extraction and solutions to meet the regulatory requirements of various states and regions in North America. Results demonstrate why utilization of positive pressure SPE on automated platforms such as the Biotage ExtraheraTM provides an innovative approach to performing EPH fractionations, offering improved control and consistent processing. In addition to consistent positive pressure processing, the use of ISOLUTE® EPH SPE consumables eliminates the potential risk of unwanted fraction breakthrough. Overall, the benefits of choosing solid phase extraction over other techniques are highlighted, emphasizing solvent reduction, faster processing times, higher throughput and enhanced accuracy and reproducibility. The findings of this research contribute valuable insights for laboratories seeking to optimize EPH fractionation techniques for more efficient and reliable analyses.

Analysis of Several Challenging Elements in Petroleum Products by ICP-MS
ASTM method D8110-17 details the analysis of trace contaminants such as Al, Ca, Cu, Fe, Pb, Mg, and K in light distillate products. However, other metals are also of interest and D8110-17 does provide method development flexibility to include additional elements. Challenges in analyzing petroleum products include volatility, carbon buildup, contamination, and spectral interferences. Contamination with common elements, such as Si, P and S, of solvents used to dilute petroleum samples before analysis can affect their levels of detection. However, the biggest challenges are spectral interferences. Fortunately, with the latest technological advancements in ICP-MS these challenges can be overcome. This work presents data for the analysis of Si, P, S, As and Hg in petroleum products in addition to D8110-17 method data.

Analysis of Nanoparticles in Organic Solvents by Single Particle ICP-MS with a Dynamic Reaction Cell
Metallic contamination in organic solvents can severely compromise product integrity in ultra-trace applications, particularly in the semiconductor industry. Among various impurities, metals, most notably iron (Fe), are frequently encountered and can significantly degrade both product performance and value. Single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) has emerged as a powerful technique for nanoparticle analysis, capable of detecting, counting, and sizing individual particles at concentrations as low as 100–1000 particles/mL. However, interferences — especially polyatomic species — can limit the system's detection capabilities. For example, accurate Fe nanoparticle detection is hindered by the ⁴⁰Ar¹⁶O⁺ interference on ⁵⁶Fe⁺. This work demonstrates the use of SP-ICP-MS in Reaction mode with Dynamic Bandpass Tuning (DRC) to effectively eliminate polyatomic interferences for iron and other elemental nanoparticle impurities, such as silica. This approach enables reliable detection and characterization of metallic nanoparticles in organic solvents, achieving lower size detection limits and improved analytical confidence.

Quartz for SCD Combustion Tubes
- University of Colorado, Boulder
Using quartz as the basis of SCD (Sulfur Chemiluminescence Detection) combustion tubes was reexamined, primarily aimed at improving detector performance. Research focused on the Agilent model 8355 but is applicable to other versions and competitive models. From early SCD development, quartz was used as a combustion material but suffered from an unknown high background, among other issues. The author now believes the background is due to the formation of silicon monoxide. Evidence to support this will be presented. The high background problem has been solved with the use of hybrid materials, resulting in better stability and consistency among combustion tubes.

Polymer Chromatography: Beyond MW and Polydispersity with Advanced Detection GPC/SEC
For polymer scientists, molecular weight and polydispersity are the two most critical pieces of information about a given sample. Size Exclusion Chromatography, usually carried out as Gel Permeation Chromatography, is the go-to technique to determine these parameters. From the same sample preparation, much more information about the sample can be gained than just Mw, Mn, Mz. Additional detectors including light scattering (SEC-LS or SEC-MALS), a second concentration detector (UV-VIS or dRI), and inline viscometers unlock additional information about the sample. These add-ons can also simplify calibration and verification. Column and standards selection, method development and troubleshooting basics will be covered at the end for those interested in expanding their familiarity with GPC/SEC.

Matrix-assisted laser/desorption ionization time-of-flight mass spectrometry (MALDI-TOFMS) is an effective method for analyzing polymers. However, polymers with high polydispersity can cause mass discrimination, where ion intensity decreases at higher molecular weights. We combined size-exclusion chromatography (SEC) with MALDI-TOFMS and MALDI-TOF/TOFMS to address this. In this report, we performed end-group analysis of polymer samples with high polydispersity and molecular weights below 50,000 using SEC and high-performance MALDI-TOFMS. We report (i) efficient MALDI pretreatment from SEC fractionation, (ii) improved visualization of end-group changes through remainder of Kendrick Mass (RKM) plots, and (iii) end-group analysis utilizing high mass accuracy and TOF/TOF measurements. Two polycaprolactone (PCL) samples with different end-groups were dissolved in THF and fractionated using SEC. Six fractions were collected, significantly decreasing the polydispersity index (PDI) from > 1.4 Ð to < 1.1 Ð. MALDI-TOFMS analysis revealed a series of PCL monomers and reduced mass discrimination, with isotopic peak separation achieved up to m/z 20,000, allowing precise end-group determination within < 2 ppm. Although the change in molecular weight distribution is easily observed in the mass spectra, understanding the changes in end-groups based on molecular weight is challenging. To visualize end-group changes, we converted the mass spectra into RKM plots. These plots clarified that cyclic oligomers dominated at low molecular weights, while higher weights exhibited two distinct mass distributions corresponding to different end-groups, identified as C4H10O and C4H10O3 through accurate mass and MS/MS (TOF/TOF) measurements.

Diviner: A Semi-AutoML Approach to Collaborative Model Building
Diviner is a semi-autoML approach that addresses traditional AutoML's black-box limitations by involving analysts in the model-building process. Instead of producing a single optimal model, the method creates a ranked family of models based on cross-validation performance, overfitting, and prediction error. The process includes user-assisted outlier assessment, variable selection, preprocessing exploration, and linear model calibration. Users can then select models for further refinement. Models can be linear or non-linear. The final output can be a single model, top-ranked models, or an ensemble. This collaborative approach bridges full automation and user customization, delivering improved transparency, interpretability, and model diversity while maintaining predictive accuracy.

More than 80 years after its sinking at Pearl Harbor, the USS Arizona continues to release small amounts of oil, offering a unique window into the long-term fate of submerged petroleum. This study analyzes oil from multiple leak points using bulk and molecular fingerprinting (GC-FID, GC-MS, GC×GC). The oil, a heavy fuel refined from California crude, remains chemically complex and PAH-rich despite decades underwater. Variability among leak points reflects differing weathering, while stable biomarkers enable source attribution. Findings highlight chemical heterogeneity, environmental risks, and broader implications for historic shipwrecks as long-term pollution sources.

Expanding ASTM D5623 to include heavier sulfur species
ASTM D5623 measures sulfur compounds in light petroleum liquids by a gas chromatography and sulfur selective detector up to 230°C. However, many sulfur species in these boiling ranges are not identified and classified as “unknowns.” Furthermore, sulfur species beyond 230°C are sometimes needed for sour crudes, catalyst performance and tracking environmental compliance. To expand ASTM D5623, overcoming the chromatographic challenges of separating these heavier sulfur compounds is a challenge.
In an attempt to expand ASTM D5623, many exotic sulfur species are identified along with analyzing various “out of scope” heavier boiling range hydrocarbons. This abstract will discuss what is Sulfur Chemiluminescence and the findings from this study.

Accurate oxygen characterization is critical for evaluating waste plastic pyrolysis oils (WPPOs). Oxygen can enter from PET and other oxygenated plastic feedstock, residual water, secondary reactions during pyrolysis, or non-plastic residues like cardboard and food waste. Oxygen-bearing compounds in WPPOs influence acidity, corrosion, instability, and catalyst deactivation, which limit the direct integration into refining and petrochemical operations. A variety of methods exist for characterizing oxygen, but none provide a complete oxygen profile. CHNSO analysis is one of the most practical techniques: it is fast, applies across the full boiling range, and can measure higher-boiling fractions that other methods cannot but often leaves a portion unaccounted for. ASTM D7423, by contrast, provides molecular-level speciation, but is limited to fractions boiling below 200 °C. In this work, we compare CHNSO and ASTM D7423 and extend insights to high-boiling fractions by correlating bulk CHNSO composition with oxygenate content in low-boiling oils.

In comparison to mechanical and biological technologies, plastic pyrolysis as part of a chemical recycling drew a great attention for its economic and environmental benefits. It can convert plastic waste into WPPO which can be used as a fuel or valuable raw petrochemical materials. A sample WPPO is shown in Figure 1. Pyrolysis is a possible route to utilize non-biodegradable materials as several countries are struggling with managing plastic waste. Pyrolysis of mixed plastic waste generates 50% less CO2 compared to energy recovery i.e., incineration. In addition, pyrolysis oil has several aromatic and aliphatic chemical components. Those components are quite diverse in their chemical properties as they may be cyclic, saturated, non-saturated, having long carbon chains and containing different elements such as sulfur, nitrogen, and oxygen. Analysis of the chemical elements in the WPPO is critical to value its environmental impacts. Sulfur and nitrogen can change the chemistry of the water by acidifying it and fertilize the soils. Consequently, it can negatively impact on the plants and the aquatic life. Moreover, sulfur and nitrogen can negatively impact oil refining processes by its corrosive effect and poisoning of the catalysts. Thus, it is of a great importance to quantify the sulfur and nitrogen content in the conventional and alternative energy sources.

- LECO Corporation
- LECO Corporation
Waste plastic pyrolysis oils (WPPO) are of growing interest as a source of more environmentally friendly alternative feedstock for producing chemicals and fuels. However, as WPPO are often produced from diverse sources with varying degrees of purity and cleanliness, more comprehensive analysis becomes necessary as compounds that are not typically found in traditional petrochemical sources can be present in these oils. Targeted screening is not enough to fully safeguard processes from potentially undesirable contaminants, which can reduce efficiency of reactions and foul production lines. To fully understand the chemical composition of such complex mixtures, nontargeted analysis is essential. This presentation focuses on analysis of WPPO using an unparalleled nontarget discovery tool: comprehensive two-dimensional gas-chromatography coupled to high-resolution time-of-flight mass spectrometry (GCxGC-HRTOFMS) capable of multi-mode ionization with electron ionization (EI), positive chemical ionization (PCI), and electron-capture negative chemical ionization (ECNI). This multidimensional analysis provides not only the enhanced chromatographic resolution of GCxGC, which separates individual oil components chromatographically in an easy-to-comprehend layout of fairways of similar chemical structures, but also the powerful analyte identification abilities of complementary ionization modes that can provide both detailed structural information and the high mass-accuracy molecular formulae for individual species.

The shift from fossil-based to alternative feedstocks such as waste plastic has introduced new contaminants into refinery processes. Among these, fluorine (F) is a major concern. Currently, combustion ion chromatography (CIC) is the standard method. However, it is costly to purchase and operate, while analysis times are long limiting sample throughput.
This presentation introduces a novel approach for determining fluorine in waste plastic pyrolysis oil (WPPO). The method involves combustion of the WPPO sample, after which halogens are quantitatively captured in an absorber solution. This solution is then analyzed using a high-resolution continuum source atomic absorption spectrometer. The instruments used in this process are called ICprep, which features self-optimizing combustion, and contrAA 800 G, which is also suitable for metal analysis and can handle smaller sample volumes than ICP-OES.
We demonstrate that CIC and the novel “ICprep + contrAA” method yield comparable fluorine concentrations in WPPO. Additionally, sample throughput increases by a factor of 3 using the new approach.

A new gas chromatography with vacuum ultraviolet absorption spectroscopy detection (GC-VUV) technique for determining simulated distillation of middle distillates will be introduced. Traditional gas chromatography simulated distillation uses a non-polar column to elute components in order of boiling point. The known boiling points of n-paraffins are used to calibrate the time axis. The boiling range distribution of a sample run under the same conditions can thus be obtained. GC FID simulated distillation uses cumulative time slices to determine BP distribution and cut points. ASTM D8267 (aromatics in jet fuel) and ASTM D8368 (aromatics and FAME in diesel fuel) are specification approved GCVUV methods that use time interval deconvolution to determine hydrocarbon types. These GCVUV sequential time intervals contain holistic hydrocarbon type quantitative information. A new GCVUV software feature allows the calculation of BP distribution and cut point intervals without modification of the standard GCVUV instrument parameters. The BP data is available in total % off by mass and volume. Additionally, a saturates only and aromatics only BP distribution can also be obtained. GCVUV BP distribution data will be compared to ASTM D2887 BP distribution data from jet fuel and diesel fuel proficiency test samples.

Considerations include material compatibility of wetted parts, temperature and pressure ratings, serviceability, flow requirements (Reynolds number and density), and direction of flow relative to the optical path. Discussion will focus on the fiber optic-based process spectroscopy of semitransparent liquids suitable for transmission measurements, with specific examples from a diesel fuel blending process, and from a synthetic fiber manufacturing facility. When considering a fit-for-purpose NIR or UV/VIS sample interface, care must be taken to ensure the vendor design constraints match your requirements. Differences between the sample interface in the lab and the in situ probe can cause the disagreement between the lab and the process.

Attendees are encouraged to bring up their own unique problems for open discussion.
1. How Different Pneumatic Nebulizers Affect your ICP-OES Elemental Analysis: From Crude Oils to Brine Samples. By Jesus Antonio Acapulco Jr, Application Specialist at Analytik Jena US LLC. The nebulizers used in inductively coupled plasma – optical emission spectroscopy (ICP-OES) have undergone significant transformation in recent years, driven by technological innovation, regulatory demands, and expanding applications across industries. The study focuses on two pneumatic nebulizers. The challenges of analyzing real world samples from difficult crude oils to brines with high total dissolved solids (TDS), are presented and discussed.
2.Tired of Clogged Nebulizers? The Effect of Novel Nebulizers on Challenging Organic ICP-OES and High TDS Aqueous ICP-MS Samples. By Randy S Rarig Jr. Ph.D. Global Physical Analysis R&T Advisor at Ketjen Corporation. Analytical laboratories increasingly face challenging samples that demand both lower detection limits and faster turnaround. These samples are often difficult to digest or dissolve, leaving residual particulates and solutions with high total dissolved solids (TDS). As a result, clogged nebulizers interrupt analyses, requiring cleaning or unblocking and reducing overall productivity. Novel nebulizers have been applied to address these challenges, demonstrating strong resistance to clogging and enabling continuous operation with little to no downtime. The result is increased throughput, faster turnaround, greater reliability of results, and enhanced confidence in data quality—benefits critical to any analytical laboratory.
3. Cutting Costs and Downtime with Robust Low Maintenance ICP-OES Nebulizer. By Jerome Franks, LabTech1 Supervisor at Hunt Refining Inc. A refinery analytical laboratory processes a wide variety of petrochemical samples, from crude oil to light, heavy, and gas oils, as well as diesel and naphtha. Previously, extensive maintenance and daily cleaning were required, while frequent nebulizer blockages led to replacement of several units per month and costly downtime. Since implementation of a robust nebulizer, the laboratory has handled all sample types reliably, requiring cleaning only once every two months with no replacements. This transition eliminated recurring costs, reduced personnel workload, and significantly improved laboratory efficiency and overall operational reliability.

PFAS (per- and polyfluoroalkyl substances) are a group of highly persistent chemicals that are now recognized as a global concern. While much attention has focused on water and soil, PFAS can also be emitted into the air during industrial processes, product use, and waste handling. Once airborne, they may travel long distances, making air a critical pathway for dispersion and exposure. Testing for PFAS in air is challenging. They can exist both as vapors and bound to particles, they occur at very low concentrations, and background contamination can easily compromise results. For industry and environmental consultants tasked with source emission testing and environmental monitoring, understanding these challenges and the expectations of regulators is essential. This presentation is designed to give attendees a clear overview of the current landscape for PFAS air monitoring. We will outline practical considerations for sampling and analysis, highlight the importance of contamination control, and provide updates on U.S. and international efforts toward method development, standardization, and regulatory guidance. Example workflows using thermal desorption coupled with GC–MS (TD–GC–MS) will also be discussed, showing how these techniques can be applied to real-world PFAS air testing. By clarifying what is expected of industry, regulators and consultants, and by sharing both U.S. and global perspectives, the session will equip participants with the knowledge needed to approach PFAS air testing with confidence and consistency.

Overview of PFAS Testing and Regulations
Per- and polyfluoroalkyl substances (PFAS) have been used in many industries from non-stick cookware, firefighting foams, food packaging materials, semi-conductor manufacturing to electric vehicle battery manufacturing. Since the late 1940s, these 100% man-made chemicals provided great benefits in our daily life as well as threats to our environment. For the past few years, with regulatory emphasis on environmental protection, there have been numerous studies regarding how to effectively measure PFAS in various sample types. In this presentation, I will go over the current regulatory landscape and discuss currently available technologies for measuring PFAS accurately.

Streamlined PFAS Analysis in Biosolids, Tissue, Soil by LC-MS/MS
While per- and polyfluoroalkyl substances (PFAS) have been analyzed by many laboratories in the past decades, most of the testing were focused on drinking water analysis globally due to strict regulations in drinking water. Now the expansion of the scope of PFAS measurements is headed toward biosolids, tissue samples, soil and many other challenging sample types. To address this US EPA published the final version of Method 1633A. In this presentation, we will discuss how to overcome challenges in handling these complex samples matrices and automation for better productivity.

PFAS in Biosolids: Regulations and Testing Methods
Sewage sludge and biosolids have been used for land application since the early 20th century due to their agricultural benefits. Sewage sludge treatment does not specifically remove PFAS, and treated biosolids can therefore contain these persistent contaminants. PFAS contamination in biosolids has received growing attention nationwide, with some cases drawing national media coverage. There are currently no federal regulations limiting PFAS concentrations in land-applied biosolids, but some states have enacted PFAS-specific regulatory limits, and several others have proposed legislation under review. This review summarizes the current regulatory landscape surrounding PFAS in biosolids and provides an overview of applicable analytical methods.

The pyrolysis of mixed plastic waste is a promising advanced recycling technology. The refinement of mixed plastic waste pyrolysis oils can be challenging because of the variable composition and properties of the oils. Methods are needed to characterize pyrolysis oils. Supercritical fluid chromatography (SFC) was investigated for the separation of pyrolysis oils. A method was devised to differentiate pyrolysis oils that are generated from polyethylene and polypropylene feedstocks using ultraviolet detection. SFC was also used with fraction collection to fractionate the oils for subsequent gas chromatography (GC) analysis. GC with mass spectrometric and vacuum ultraviolet spectroscopic detection were used.

Waste plastic pyrolysis oils (WPPOs) are complex, variable mixtures. Unsaturation governs stability, upgrading severity, and the quality of fuel-range cuts. Reliable, transferable olefin quantification across whole oils and distillates is therefore essential. Here is presented an advancement over our prior gasoline-range method, extending precise quantification to jet-range fractions and progressing toward diesel-range application. The approach couples comprehensive two-dimensional gas chromatography with flame ionization detection (GC×GC–FID) with targeted derivatization to reposition olefins in the GC×GC space, enabling robust indirect quantification with carbon-number- and class-resolved outputs amid paraffins, naphthenes, and aromatics.

Plastic waste manifests as environmental microplastics (MPs) and, when thermochemically processed, as waste plastic pyrolysis oils (WPPOs), both demanding rigorous measurements. Analytical measurements underpin efforts toward the conversion of plastic waste into usable products and toward understanding the organic compounds associated with MPs. Current economics are challenging; however, analytics can help reduce risk and cost. This talk surveys work on the detailed analysis of WPPOs and MPs. A forward-looking perspective will outline research and implementation needs over the next five years to support broader use of WPPOs, alongside the role of education and public communication in building literacy and trust. The talk highlights opportunities for researchers and industry to reduce uncertainty, align expectations, and support responsible deployment.

Due to their environmental persistence and potential implications on human health, the analysis of per- and polyfluoroalkyl substances, or PFAS, in the environment remains critical. Targeted analysis using LC-MS/MS has long been the analytical method of choice, due to its high sensitivity and specificity. With more than 3000 potential PFAS-type compounds, targeted analysis does not always allow for the assessment of the total impact of these compounds. Because of this, there has been increasing interest by regulatory committees in non-targeted analysis techniques, such as quantifying total organic fluorine (TOF), as a PFAS impact assessment. Combustion Ion Chromatography, or CIC, allows for the sensitive quantitation of TOF, ranging from single digit ppb to percent levels. In this technique, samples are combusted in a high temperature oven, where organofluorine bonds are broken to produce HF, which is subsequently absorbed into solution and analyzed by IC for fluorine. Prior to analysis by IC, inorganic, or free fluoride must be separated from the sample to prevent interference. A variety of techniques exist to accomplish removal of inorganic fluoride, such as the AOF (adsorbable organic fluorine) method (USEPA Method 1621), which captures organofluorine compounds on an activated charcoal bed and allows for removal of free fluoride through a rinsing step. The charcoal can then be analyzed by CIC. Other methods have also been investigated to further improve recovery of TOF, allowing for the non-targeted identification of PFAS compounds ranging from C1-C16+. Most recently Metrohm USA and Markes International collaborated to introduce “Total Fluoride in Air by C-IC”. A complete portfolio of Total Fluorine analysis in Air, Water and Soil will be presented.
