ABSTRACT:
A method and system for monitoring a concentration of volatile organic constituents in a test sample. A sparging vessel separates a volatile organic constituent sample from the test sample. A dryer dries the constituent sample to remove any vapor therein by mixing the constituent sample with a drying agent. A sorbent trap adsorbs the volatile constituents from the drying agent and concentrates the purged constituents. A microprocessor controlled director valve selectively directs the constituent sample from the dryer to the sorbent trap and from the sorbent trap to an organic vapor detector for determining the concentration of volatile constituents and for generating an electrical signal proportional to the total concentration of the volatile constituents in the sample.
