Refurbished Purge and Trap, Tekmar LSC 2000

Purge and Trap (P&T) has been used for decades to extract volatile organic compounds (VOCs) from a solid or liquid matrix for introduction into a Gas Chromatograph (GC) for separation and identification. The VOCs are concentrated onto an adsorbent trap, followed by thermal desorption into a GC. Sample matrices can range from soil, plastics, foods, flavour, fragrance, emulsions and water.
