CENTURION

The CENTURION is available as a combined water/soil purge and trap autosampler or water only system from EST analytical. Purge and trap refer to the headspace technique in which volatile organic compounds (VOCs) are purged out of the sample matrix by an inert gas and carried onto a sorbent trap, where they are concentrated and later introduced into an instrument (e.g., gas chromatography (GC) or GC/mass spectrometry (MS)) for analysis.
