高纯四氯乙烯纯度测试方法的改进

Improvement for quantitative determination method of high purity tetrachloroethylene

对应用带分流/不分流进样口和氢火焰检测器的气相色谱(GC-7890N),以CP-SIL 8 CB 50 m×0.32 mm×5μm(瓦里安提供)毛细管柱为分离柱,对高纯度四氯乙烯中各有机杂质组分的测试方法进行了广泛探索研究,得到的方法具有精密度好、准确度高、操作性强等特点,其有较高的推广价值。

This article focused on the application with gas chromatography （GC-7890N） with split/splitless inlet and hydrogen flame detector（FID）, with CP-SIL 8 CB 50m^＊0.32mm^＊5um （provided by Agilent ）for the capillary column, carried out extensive exploration and research methods of testing organic impurities in the high purity tetraehloroethylene. Finally, the method has been to explore has good precision, high accuracy, easy to operate, there are a lot of promotional value.
