顶空气相色谱法测定聚乙烯中环已烷含量

Measurement of Cyclohexane Content in PE by Headspace Gas Chromatography

建立了用顶空气相色谱法测定聚乙烯中挥发性烃类的分析方法。讨论了平衡时间、平衡温度、气-固体积比等因素对测定结果的影响。方法的相对标准偏差（BSD%）为1.0%-4.0%。方法快速、准确、重复性高。

The analysis method of measuring volatile hydrocarbons in PE by headspace gas chromatography was established. The impact of the balance time, balance temperature and gas-solid volume ration on the measurement was discussed.
