The determination of vinyl chloride (VC) in polyvinyl chloride (PVC), vegetable oils, food-simulating solvents, mouthwashes, and blood anticoagulant solutions by gas-liquid chromatography is described. PVC polymers are disolved in either tetrahydrofuran or dimethyl acetamide. Vegetable oils are diluted with an equal volume of tetrahydrofuran. The resulting solutions are injected into a gas-liquid chromatograph equipped with a flame ionization detector. Mouthwashes, blood anticoagulant solutions, and 3 food-simulating solvents, 3% acetic acid, 50% ethanol, and heptane, are analyzed by direct injection into a chromatograph. Sensitivities are such that 0.05 ppm VC in solution or 1 ppm VC in PVC can be quantitated.
本文描述了通过气液色谱法测定聚氯乙烯（PVC）、植物油、食品模拟溶剂、漱口水和血液抗凝剂溶液中的氯乙烯（VC）。PVC聚合物可溶于四氢呋喃或二甲基乙酰胺。植物油用等体积的四氢呋喃稀释。将所得溶液注入配备火焰离子化检测器的气液色谱仪中。漱口水、血液抗凝剂溶液以及3种食品模拟溶剂（3%乙酸、50%乙醇和庚烷）通过直接注入色谱仪进行分析。灵敏度足以定量溶液中0.05 ppm的VC或PVC中1 ppm的VC。
