Abstract
A thermally-releasable-sample collecting device is provided comprising a pistol-shaped casing, a blunt ended probe in the front end of the casing barrel, an adsorber tube locating collar in a rear end of the casing barrel, and an adsorber tube slidably located in the collar and having an open ended, sample adsorber end portion in a central portion of a gas passage extending through the probe. The adsorber tube has a closed rear end and gas ports which are located by a spring loaded plunger in a first position for drawing air through the probe into the adsorber tube, and a second position where carrier gas passes along the adsorber tube, to entrain thermally released sample, while the sample adsorber end portion is protruding from the probe into the heated entry of an analyzer.
