Welcome to the RESTEK/SHIMADZU Petrochem GC Applications workshop. Because of the need for more accuracy in refinery environments, customers are asking for a closer look at existing analytical techniques. The industry is looking for different approaches to monitor their refining processes. ASTM, as the leading standardization body for this industry, is making changes to existing methods to meet the industry’s needs. We will also be covering several new and modified GC configurations for analysis, including the new Nexis GC-2030 from Shimadzu. Please, join us for what is sure to be an informative discussion.

This workshop will provide an overview of various Petroleum Applications using Gas Chromatography. Covered topics include System and Custom GCs as well as Petroleum Applications Trends and ASTM Developments.

Techniques to speed up the analysis in gas chromatography

Read abstract

In this seminar, we will discuss options to reduce the analysis time in gas chromatography without major investment in equipment nor investment in time to redevelop existing methods.

Ways to speed up the analysis depends on the resolution between the components of interest. Whenever there is plenty of resolution between the compounds the analysis time can be decreased by simply shortening the column or increasing the flow rate. However, in cases where we do not have extra column efficiency, the options are to switch to a more efficient carrier gas or use shorter, narrow bore, thinner film columns. Regardless of the choice, to maintain the elution order between the compounds or preserve resolutions, the methods have to be properly translated.

Practical examples will demonstrate:

  1. Using Restek’s EZGC method translator to speeding up the analysis while scaling down to smaller, high-efficiency, narrow-bore columns.

  2. Presented will be a migration of ASTM D2887 simulated distillation from a slower procedure A to faster procedure B using a slow, 120V oven and the GC Accelerator kit. The GC Accelerator kit provides a simple way to speed up sample analysis. By reducing oven volume, these inserts allow faster ramp rates to be attained.

  3. Speeding up a DHA run by increasing the flow on a long, narrow bore column.


#256 - Applicability of micro packed columns (1/16" x 1 mm id) packed with DiatoSorb solid support and configured for use in a dedicated capillary Agilent 6890 and 7890 GC

Columns and packings made with DiatoSorb solid support are superior in performance and reproducibility because Restek is the only global supplier that completely controls the physical and chemical properties of chromatographic-grade diatomaceous earth. This poster will demonstrate the performance, inertness, and speed of analysis obtained using Sulfinert-coated stainless steel micro packed columns (1/16 inch OD x 1 mm ID) compared to traditional packed columns (1/8 inch OD x 2 mm ID). The micro packed columns are easily installed and configured for on-column injection in a dedicated capillary Agilent 6890 or 7890 capillary GC as well as in a standard packed column GC.

#258 - Solutions for analysis of FAME Biodiesel quality using gas chromatography

Read abstract

Fatty Acids Methyl Ester (FAME) biodiesel is currently the most popular alternative fuel on the market. Biofuel burns cleaner and emits fewer greenhouse gases than traditional sources of energy. Therefore, it also makes for an environmentally friendlier option.

FAME biodiesel is made from animal or vegetable fats with transesterification using acidic or basic catalyst and alcohol. All the steps of the reactions are strictly monitored and the final product is evaluated for reaction yields, residual starting materials, and byproducts. Presented will be solutions for determination of the final FAME content, residual alcohols, and glycerol/glycerides using gas chromatography.
