Utilization of Hydrogen Carrier Gas on a High Resolution GC-TOFMS System: An Application Compendium

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.
