摘要：提出了气相色谱-质谱法测定乙二醇二缩水甘油醚中环氧氯丙烷残留量的方法。样品5.000 0 g置于10 mL容量瓶中,用乙醇稀释并定容。所得溶液经超声处理后,采用HP-5MS毛细管柱、载气程序升流和柱程序升温进行气相色谱分离。质谱分析中采用电子轰击离子源和选择离子监测模式。环氧氯丙烷的质量浓度在12.06~602.97 mg·L^(-1)范围内与其峰面积呈线性关系,测定下限(10S/N)为4.21 mg·L^(-1),测定值的相对标准偏差(n=8)为0.51%。按标准加入法进行回收试验,回收率在94.2%~97.1%之间。
Gas chromatography-mass spectrometry （C-C-MS） was proposed for determination of residual amounts of epichlorohydrin in glycol diglyeidyl ether. The sample （5. 000 0 g） was placed into 10 mL of volumetric flask, diluted and made its volume up with ethanol. After ultrasonic treatment, the solution obtained was separated through HP-SMS capillary column by GC at carrier gas flow programmed and column temperature programmed. Electron impact ion source （EI） and selected ion monitor （SIM） mode were adopted in MS analysis. Linear relationship between values of peak area and mass concentration of epichlorohydrin was obtained in range of 12.06- 602. 97 mg · L^-1, with lower limits of determination （10S/N） of 4. 21 mg · L^-1 and value of RSDs （n=8） of 0. 51%. Test for recovery was made by standard addition method, giving results in the range of 94. 2%-97. 1%.
