Abstract # 106 - Paper

New Developments in Low Level Sulfur Measurement

Michael Pohl - HORIBA Instruments International, Scientific Division

New Low Sulfur Analytical Requirements

The permitted levels of sulfur in various fuel samples continues to drop due to EPA Regulations, creating a new series of challenges for the manufacturers of analytical instruments to solve. Most of these petroleum streams are relatively pure, but often additives are introduced which complicates the analysis. In these cases, the Limit of Detection of the method becomes a less challenging issue than the effects of interfering elements. Examples of these effects will be illustrated for real world samples run on commercially available instruments. These case-by-case examples will be discussed to illustrate possible solutions.

The Analysis of Regulated Phthalates in a Complex Matrix using Thermal Desorption-GC/MS

Rojin Belganeh - Frontier Laboratories America
Terry Ramus, Ph.D - Frontier Laboratories America
Itsuko Iwai - Frontier Laboratories America

Phthalates are used as additives in plastic for many years to make them more flexible.  Several phthalates are regulated on a global scale, and several analytical techniques can be used for phthalates analysis.  Thermal Desorption (TD)-GC/MS is one of the easiest and most accurate methods for phthalate analysis. Recently manufacturers have switched formulations to include unregulated phthalates. Generally, phthalates are identified using both retention time and MS spectra. However, some unregulated phthalates have similar retention times and MS spectra, compared to regulated phthalates. This is the basis of existing ASTM and IEC methods for regulated phthalates by this technique.

Characterization of Hydrocarbons in Shale Rock Using Multiple Modes of Pyrolysis-GC/MS

Terry Ramus, Ph.D - Frontier Laboratories America
Rojin Belganeh - Frontier Laboratories America
Itsuko Iwai - Frontier Laboratories America

Hydrocarbon-based petroleum continues to be the most cost-effective energy source. The importance of Rock Evaluation Pyrolysis and the presence of specific compounds in source rock is of immense significance in assessing the potential of a given play. Although some laboratories continue to solvent extract the sample before analysis, others have found thermal extraction of the source rock will often yield a faster more accurate determination of the organic content. This is because most organic material is not accessible via traditional liquid extraction. This work demonstrates the applicability of multiple modes of Pyrolysis-GC/MS without solvent extraction or sample pretreatment before analysis.  

Abstract # 114 - Paper

Analysis and Characterization of Coals using Multiple Modes of Pyrolysis-GC/MS

Terry Ramus, Ph.D - Frontier Laboratories America
Rojin Belganeh - Frontier Laboratories America
Itsuko Iwai - Frontier Laboratories America

Analysis of coals for potential petroleum related content is of immense significance for fuel evaluation.  Pyrolysis-GC/MS is a very flexible technique which can be used sequentially in multiple modes to characterize different types of coals chemically. This presentation uses a range of PY-GC/MS application examples to illustrate the utility of information obtained from different PY-GC/MS modes of use. A strategic “method map” approach will be described utilizing multiple techniques such as Evolved Gas Analysis, thermal desorption, and flash pyrolysis using Pyrolysis GC/MS techniques to characterize the differences among three coal samples for comparative analysis.

Abstract # 115 - Training Course

Gas Chromatography Made Simple

Lee Polite - Axion Analytical Laboratories, Inc.

Gas Chromatography (GC) is one of the world's most popular analytical tools, yet very few people understand how it works.  Anyone can push buttons, but most analysts are not quite sure why they are pushing the buttons.  During this talk, we will unveil all of those mysteries and get you to understand how the underlying technology works.  The best kept secret is that GC is totally understandable.  By the end of this short course, not only will you understand how GC works, but you will also be very comfortable developing a GC method from scratch, including choosing the correct column length, diameter, film thickness, stationary phase, flow rate, inlet, detector, etc.

Abstract # 117 - Paper

Fast Analysis of Middle Distillates using Gas Chromatography – Vacuum Ultraviolet Spectroscopy

Alex Hodgson - VUV Analytics, Inc
Jack Cochran - VUV Analytics, Inc

Middle distillates like jet fuel and diesel have strict requirements regarding aromatic content to reduce pollution and maximize engine life. The current referee method, ASTM D1319, is becoming unsustainable as remaining dye stocks wane. Current alternative methods include supercritical fluid chromatography (SFC) and high-performance liquid chromatography (HPLC). Vacuum ultraviolet (VUV) spectroscopy is a relatively new GC detection methodology that can analyze jet fuel in less than 14 minutes and diesel in less than 20 minutes. Automated quantitation using time interval deconvolution (TID) can determine total mono- and di-aromatics for jet fuel and total mono-, di-, tri-, and tetra-aromatics for diesel.

Abstract # 121 - Paper

Hydrogen and Nitrogen as Carrier Gas Alternatives to Helium: Gas Chromatography – Vacuum Ultraviolet Spectroscopy of Hydrocarbon Groups and Select Compounds in Gasoline-Range Samples

Ryan Schonert - VUV Analytics
James Diekmann - VUV Analytics
Alex Hodgson - VUV Analytics
Jack Cochran - VUV Analytics

ASTM D3606 (benzene), ASTM D5599 (ethanol, oxygenates), and ASTM D5769 (benzene, toluene, total aromatics) gasoline tests typically require three dedicated GC systems, all using helium carrier gas, which is in short supply.  ASTM D8071-17, PIONA and oxygenates analysis with gas chromatography – vacuum ultraviolet spectroscopy (GC-VUV), allows benzene, toluene, total aromatics, and ethanol, as well as other parameters, to be accomplished on one GC in less than 35 min.  

Helium use can be eliminated entirely by employing alternate GC carrier gases, such as hydrogen and nitrogen.  This presentation will demonstrate how using GC-VUV for the analysis of gasoline-range samples.

Abstract # 123 - Paper

KEYNOTE SPEAKER - Portable Capillary Chromatography

Dr. Milton Lee - Brigham Young University

Most current chromatographic instrumentation has been designed for stationary use on a laboratory bench; however, this situation is rapidly changing as analysts become more interested in smaller systems, faster analysis and portability. Portability can merely provide easy movement within the laboratory to facilitate coupling to other instruments or apparatus, installation in a manufacturing facility, or transport to remote locations for field use, such as environmental monitoring. On-site analysis eliminates problems related to loss of sample integrity during transport and storage, and greatly reduces the time required for testing and reporting.

 With respect to both gas chromatography (GC) and liquid chromatography (LC), electrical power usage, column robustness and interfacing, and minimization of consumables for compliance with green chemistry principles, have become the most difficult challenges, especially when the preeminent desire is to retain high chromatographic performance. Advances in resistive heating technologies and microchip column formats have been made to address requirements for portable GC, but interfacing and temperature uniformity can be a challenge. In LC, nano-flow capillary columns have been developed, but minimizing detrimental extra-column volumes in connections and developing sensitive detection for small columns are difficult challenges. For both GC and LC, sample preparation and injection into the chromatograph are the most difficult and time-consuming operations.

 In this presentation, advancements in portable GC, GC-MS and nano-flow LC that have led to instrumentation that has recently been commercialized will be described. Theseinclude robust capillary column technologies for both GC and LC (open tubular, packed capillaries, and microchip columns), novel temperature programming techniques forhigh temperature GC, calibration and sampling for portable GC-MS, “plug-and-play” column cartridges for nanoflowLC, and serial LC column arrangements with dual-wavelength on-column UV-absorption detection for positive target analyte detection. Applications in the areas of petroleum and fuels, environmental analysis, and process stream monitoring will be described.
