Sensitive trapping and gas chromatographic method for vinyl chloride in air samples.
A simple and sensitive method is described for determining vinyl chloride monomer in air. Vinyl chloride monomer from a sample of air is trapped onto a Tenax GC trap cooled with Dry Ice. The trap is installed on a gas chromatograph by a simple valve arrangement. The trap is heated, and the entire sample is flushed onto the gas chromatographic column. Vinyl chloride is determined at 6 and 60 ppb (v/v) levels with recoveries ranging from 79 to 104%.
