In a previous study of methods and instrumentation for measuring trace amounts of the total effluvai from man, only 12 compounds were identified. In the present study, using refinements of the methods, over 135 effluents have been identified. Two to three times this number of compounds were observed in the sensitive gas chromatograph-mass spectrometer GC-MS analytical system, but could not be identified. A variety of organic structures are included among these effluents. In addition to alcohols and ketones, unsaturated, branched, cyclic and aromatic hydrocarbons, sulfhydryl and cyano and a variety of heterocyclic compounds were found. The most significant change in the method is the replacement of the cryogenic collection system with porous polymer collectors. The latter can be used to collect effluents at room temperature, to absorb more effluents in a shorter time, can be connected in parallel to the chamber, and can be cleaned and desorbed without using vacuum.
