摘要：A procedure for determination of a micro-amount of vinyl chloride monomer in environment is described. In this method, a modified concentration tube containing fire brick C-22 and 5% PEG 400 on Chromosorb WAW was used. The tube was cooled with Dry Ice methanol and sample gases collected in a sampling bag from atmosphere or evaporated from water by aeration was passed through the tube. Vinyl chloride monomer and other organic gases were condensed on the fire brick C-22. Temperature of the tube was raised to room temperature and vinyl chloride monomer was introduced into a gas chromatograph, by which a greater part of other organic gases remained on the 5% PEG 400 on Chromosorb WAW. By this procedure, as little as 0.3 ppb of vinyl chloride monomer in 1 liter of atmospheric air, 0.01 ppb of vinyl chloride monomer in 100 ml of water can be determined without interference of co-existing organic substances.
