The Passive Sampler for Organic Vapors collects organic vapors without the use of a pump. The sampler is validated for short-term and eight-hour sampling and 24-hour indoor sampling for some compounds. Use the sampler to test exposure to VOCs such as toluene, tetrachloroethylene, trichloroethylene, xylenes, ethylbenzene, 2-butanone (MEK), hexone (MIBK), benzene, butyl acetates, and styrene.
