摘　　要：采用全自动顶空进样器、氢火焰离子化检测器及气相色谱仪分析了三元乙丙橡胶中己烷和乙叉降冰片烯(ENB)的残留含量。结果表明,己烷与ENB加标回收率均在90%(质量分数)以上,分析结果的精密度分别为94.4%、96.8%,准确度均在95%以上,检出限:己烷为0.091μg/g、ENB为0.085μg/g,两种组分的线性范围均大于102,线性相关性均在0.999以上。This method uses the automatic headspace sampler,hydrogen flame ionization detector,and gas chromatography to analyze the residual ethane and ethylidene norbornene in the ethylene-propylene rubber.The results show that the recovery rates of hexane and ethylidene norbornene are both above 90%(mass fraction),and the precision of the analysis results is 94.4%and 96.8%,respectively.The accuracy is above 95%.The detection limithexane 0.091μg/g,and ENB 0.085μg/g.The linear range of the two components is greater than 102,and the linear correlation is above 0.999.
