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.

Abstract # 111 - Workshop

The Pyrolysis Workshop

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

Pyrolysis performed correctly is a valuable and easy to use sample introduction technique for GC and GC/MS.  It allows the user to characterize any solid or viscous organic materials that otherwise could not be analyzed by GC.  Learn when to use Evolved Gas Analysis, Thermal Desorption, Heart-Cutting, or Pyrolysis; all with the same system. Potential, new and existing users of Frontier Labs’ Multi-functional Pyrolyzer products are encouraged to attend. No prior experience needed.  

Topics: 
-Materials characterization “method map”: a formula for success.
-Applications: deformulation, polymers, additives, coatings, biomass, oil shale, quantitative methods.
-Data Review Tools: hands-on use of F-Search Software and MS Libraries.
-Maintenance and Discussion Sessions.

Abstract # 112 - Paper

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

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.

Abstract # 113 - Paper

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

Terry Ramus, Ph.D - 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.
