摘要
利用气相色谱－ 质谱联用法对工业异丙苯中的有机杂质进行了定性分析。通过阿匹松填充柱、 Ｆ Ｆ Ａ Ｐ 和 Ｓ Ｅ－ ５４ 石英毛细管柱气相色谱对工业异丙苯有机杂质的分离比较可知，后者分离效果最佳。１３ 种有机杂质可以被同时检测，并利用校正面积归一化法建立了定量分析方法。实验同时发现该方法具有良好的准确度和精确度，可以应用于工业异丙苯的中控分析。
The organic impurities in industrial isopropyl benzene were determined by the techniques of combined gas chromatography/mass spectrometry. Apiezon filled column, FFAP and SE-54 capillary column gas chromatography for the separation of industrial isopropyl benzene product were compared,and SE-54 was found the excellent capillary column for the determination of isopropyl benzene and its organic impurities. Thirteen kinds of organic impurities could be determined at one experiment. The quantitative analysis method was built using corrected area normalization with well degree of accuracy and precision.
