Purge and Trap concentrators, new and refurbished.

The purge and trap apparatus is used to gently extract volatile compounds from a liquid at room temperature. Typically, the liquid is water. In the center is the purging tube. Purge gas is bubbled through the liquid in the purge tube and collected on the trapping column on the left. The trapping column generally contains a solid adsorbent. After a predetermined amount of purge time, the temperature of the trapping column is quickly raised and the compounds that were trapped on the trapping column are driven off of the trapping column and onto the chromatographic column.

Purge and trap techniques involve the forcing of a gas (usually helium) through a sample of water or soil slurry, which entrains the VOCs. The entrained volatiles can be fed directly into the analytical instrument or can be used in combination with the sorbent trap to concentrate samples for later thermal extraction.
