ABSTRACT:
A diffusive sampler for effectively determining chemical vapor levels, the ampler having a thin pouch-like container made up of an impermeable back sheet and a selectively permeable front membrane attached thereto along its peripheral edges. The front membrane is made of a material capable of passing preselected vapors therethrough and for preventing other preselected vapors from passing therethrough and preferably has substantially the same permeation rate as human skin. Located within the pouch-like container is an adsorbent substance for adsorbing the chemical vapor and for providing information with respect to the chemical vapor levels adsorbed thereby. In use a plurality of the samplers are adhered to the skin of an individual wearing a protective garment to establish the effectiveness of the garment when subjected to specific chemical vapors.
