A gas chromatographic method for the determination of the mixture of organic solvents in air has been developed. The optimum conditions of the separation of the mixture were obtained in the column packed with 10% UCON HB 2000 coated on Chromosorb W AW DMCS 80-100 mesh. The components of the mixture are collected on activated charcoal and desorbed with CS2. A quantitative analysis is made using methyl isobutyl ketone as an internal standard. The lowest detectable limit under proposed air sampling and analysis conditions is 0.1 TLV (threshold limit value) for each component of the mixture.
已开发出一种气相色谱法用于测定空气中有机溶剂混合物。在填充有涂覆于80 - 100目Chromosorb W AW DMCS上的10% UCON HB 2000的色谱柱中获得了混合物分离的最佳条件。混合物的各组分收集在活性炭上，并用二硫化碳解吸。使用甲基异丁基酮作为内标进行定量分析。在所提出的空气采样和分析条件下，混合物各组分的最低检测限为0.1阈限值（threshold limit value，TLV）。
