Analysis of the Relationship between Purge and Trap and Static Headspace
Dynamic headspace is achieved by passing an inert gas through a liquid sample (or solid surface) to purge out the components to be analyzed, allowing them to be enriched in a container filled with adsorbent. Then, the adsorbent is heated to desorb the adsorbed components, which are then carried by a carrier gas into a gas chromatography column for analysis.
