ABSTRACT:
A method, and air sampler concentrator, for sampling and detecting trace quantities of amine vapors in ambient atmospheres, are described. Atmospheres containing vapors of amines, particularly aralkyl amines such as amphetamines, are sampled and vapors collected in a concentrator having two adsorber components, one a polymeric adsorbent for amines and the other a selected alkaline adsorbent. Collected vapors are thermally desorbed in stages and the amine vapors analyzed by gas chromatography. The concentrator and method are very suitable for detecting trace amount of amine drugs and alkyl or arylalkyl amine vapors found in some industrial work environments.
