Determination of Trace Contaminants in Air by Concentrating on Porous Polymer Beads

Abstract

A method has been developed for concentrating gas samples at room temperature on porous polymer beads which eliminates the use of cold traps or cold columns, and gives on-column injection. The gas sample is concentrated on the same column that is subsequently used for the gas chromatographic analysis. It was felt that the microcoulometer was potentially the best detector for chlorinated hydrocarbons. The authors discuss the detection of various halogenated hydrocarbons.
