Evaluation of a New Analytical Trap for Gasoline Range Organics Analysis

Purge and Trap (P&T) is a concentration technique used for the analysis of Volatile Organic Compounds (VOCs). The major component of any P&T system is the analytical trap. This trap is responsible for trapping the analytes purged from the sample and then releasing them upon heating for further analysis by the GC and GC/MS.

This study will evaluate a new analytical trap that is designed by Teledyne Tekmar. The packing material in this new trap improves the recovery and performance of Volatile Hydrocarbon Fractions found in Gasoline Range Organics (GRO) when prepared using Purge & Trap and Headspace sample concentration techniques used in tandem with GC.
