What is Purge and Trap

Volatile organic compounds are purged from water samples by an inert gas, then moved to a head space phase, captured and concentrated in a trap tube. Subsequently, the components desorbed by rapidly heating the trap tube are introduced into an analysis column.

Components can be efficiently recovered because they are forced into a headspace vapor phase by purging. Therefore, unlike static headspace sampling and SPME methods that cause their gas-liquid equilibrium changing by concentration of salt in the sample, dispersion of data due to matrix effects is less likely to occur. A salting out operation is not required.

The Purge and Trap method offers significant operational advantage.
