A simplified quantitative method is described for collection of air pollutants on a porous polymer (Tenax GC) trap, for heat desorption onto a column and for analysis by gas chromatography. The method has been applied to a number of volatile industrial substances from stacks and ambient air such as aromatics, alcohols, ketones, acids, nitro, chloro, amino, and sulfur compounds. Low-molecularweight compounds were not included.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
