Purge & Trap (P&T) concentration is a common technique used for the analysis of Volatile Organic Compounds An analytical trap is the major component of any P&T system and is responsible for trapping the analytes purged from a sample, and then after heating, releasing them for further analysis. Purge and Trap Operation Overview A measured amount of sample is placed in a sealed vessel The sample is purged with inert gas, causing VOCs to be swept out of the sample The VOCs are retained in an analytical trap, which allows the purge gas to pass through to vent. Purge and Trap is a type of dynamic headspace extraction of VOC compounds where a purge gas, such as helium or nitrogen, is passed through a sample and the VOCs are carried to a trap to concentrate them Used globally for environmental and food testing, Purge and trap can easily perform part per trillion levels of detection using GCMS.
