Utilization of Hydrogen Carrier Gas on a High Resolution GC-TOFMS System: An Application Compendium
Poster Jun 19, 2014
Joe Binkley, David Alonso
Both the costs associated with a dwindling helium supply and the need for high sample throughput have fueled the desire to develop fast gas chromatography methods using hydrogen as a carrier gas. This poster demonstrates the ability to utilize hydrogen carrier gas on a high resolution GC-TOFMS system, the Pegasus® GC-HRT. Methods and data from multiple application markets, including specialty chemicals, forensics, and metabolomics, will be displayed. Various polymer additives were used to represent the specialty chemical market, drugs of abuse were used to demonstrate capabilities in the forensic market, and a derivatized metabolite mixture designed for metabolomics research was used for the metabolomics market.

The Use of Pyrolysis/GCMS and Newly Developed Libraries to assist in Characterizing Complex Polymeric SamplesPoster
Pyrolysis-GC/MS is an effective tool in introducing and analyzing polymers. But since the polymer must be broken down to volatile segments in order to be sent to the GC, identification by the Mass Spec does not look at the original polymer, but only the fragments. This poster will look at a unique library designed to work with the existing NIST library, however contains averaged spectra of pyrolyzed polymers so it can be used to directly identify the original polymer sample.READ MORE
