ABSTRACT:
Delivery of a test specimen vapor--carrier gas mixture into a gas chromatograph is accomplished by means of an apparatus including a barrel to receive a probe which serves to maintain the test specimen in contact with carrier gas within the barrel, a heating coil disposed around portions of the barrel housing the sample, and a compression seal releasably bearing against a portion of the probe to prevent air flow into and gas flow from the open end of the barrel.
