Determination of vinyl acetate in air by gas chromatography. 1981

K S Sidhu

A gas chromatographic analysis for vinyl acetate is presented. Vinyl acetate was sampled by adsorbing on activated carbon. It was desorbed with carbon disulfide with a mean efficiency of 83.0%. The analytical column was packed with 10% free fatty acid phase on acid-washed Chromosorb-P. Gas chromatographic identification was also conducted on another column packed with 0.4% Carbowax-1500 on Carbopack A. Analysis was performed on a chromatograph equipped with a flame ionization detector. The precision (coefficient of variation) for the analytical procedure using a free fatty acid phase column was 4.0%. Based on a 10 litre air sample, the calculated limit of detection by this procedure was 0.1 parts per million.

UI MeSH Term Description Entries
D002246 Carbon Disulfide A colorless, flammable, poisonous liquid, CS2. It is used as a solvent, and is a counterirritant and has local anesthetic properties but is not used as such. It is highly toxic with pronounced CNS, hematologic, and dermatologic effects. Disulfide, Carbon
D002849 Chromatography, Gas Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
