摘    要:建立了测定醇醚产品中微量环氧乙烷的顶空气相色谱法.样品经80℃、30min静态顶空后,采用气相色谱-氢火焰离子化检测器进行检测,外标法定量.该方法加标回收率在88.3%~104.7%,相对标准偏差在0.66%~3.94%.应用此法杂质干扰少,对醇醚产品中微量环氧乙烷在0.4~25mg/kg线性关系良好(7>0.998)...

关 键 词:顶空气相色谱法  测定  微量  环氧乙烷

Abstract:In this paper,the determination method of micro ethylene oxide in the product of glyco ether by headspace gas chromatography was established.With hydrogen flame ionization detector,the detecting test was carried out.The addition standard recovery is 88.3%~104.7%.The relative standard deviation is 0.66%~3.94%.This method has many advantages as follows:simple operation,high accuracy,good repeatability,and so on.It's application has achieved good effect.
Keywords:Headspace GC  Determination  Micro  Ethyene oxide
