Separation of Interference in Gaschromatografic Quantutation of Chloroethylene in Air

Abstract

A simple method is described for separation of interference by co-existing methyl chloride and acetaldehyde in gas chromatographic quantitation of low levels of chloroethylene in air. Methyl chloride and acetaldehyde were successfully separated from chloroethylene by FID-gas chromatography using a column of 5.5% Ucon oil LB 550 X and Porapak QS. Relative deviation of peak area was found less than 5% on reproducibility of quantitative analysis, and the limit of detection was 1-4 ppb of chloroethylene.
