对工作场所空气中正己烷、三氯乙烯和四氯乙烯采用活性炭管采样,用二硫化碳解吸后进样,经FFAP(聚乙二醇)毛细管柱分离,程序升温,以氢火焰离子化检测器(FID)检测,保留时间定性,峰面积定量,通过实验条件的优化以及精密度、准确度、采样效率、吸附容量和干扰实验,确认该方法适用于工作场所空气中正己烷、三氯乙烯、四氯乙烯的同时测定。 Samples of activated carbon tubes of n-hexane, trichlorethylene and tetrachlorethylene in the air of the workplace were sampled, desorbed with carbon disulfide, and injected through a FFAP (polyethylene glycol) capillary column. The temperature of the sample was increased to a hydrogen flame ionization detector FID), qualitative and quantitative retention of retention time, and optimization of experimental conditions as well as precision, accuracy, sampling efficiency, adsorption capacity and interference experiments confirmed that this method is suitable for the air in the workplace, n-hexane, trichlorethylene, Simultaneous determination of vinyl chloride.
