Success using Alternate Carrier Gases for Volatile Methods

In this presentation from a recent 'Advances in Enviromental Analysis eSeminar' hosted by Separation Science in collaboration with PerkinElmer, Lee Marotta (PerkinElmer, USA) reports on the success of using alternate carrier gases for volatile methods.

This presentation demonstrates the success of using alternate carrier gases for volatile methods such as US EPA methods 524.2, 624 and 8260. Traditionally, these are performed using helium as the purge and gas chromatography (GC) carrier gas. However, due to its increasing cost and suggested limited supply, alternative carrier gases, such as hydrogen and nitrogen are being considered. The goal of this research was to investigate the use of alternate carrier gases while meeting US EPA method criteria.
