摘　　要：建立了气相色谱-质谱联用技术测定REACH法规中列举的乙二醇单甲醚、乙二醇单乙醚、乙二醇乙醚乙酸酯、1,2,3-三氯丙烷和N-甲基吡咯烷酮等5种高度关注物质的方法,并对色谱条件和样品前处理条件进行了优化:以丙酮为提取溶剂,超声提取,0.45μm有机相微孔滤膜过滤。在本试验研究范围内,标准工作曲线溶液呈良好的线性关系,相关系数均大于0.994。该方法简便、准确、灵敏度高,回收率较高,相对标准偏差小于10%,检测限远低于REACH法规0.1%的限量要求。A testing method of determination of 2-methoxyethanol, 2-ethoxyethanol, 2-ethoxyethyl acetate, 1,2,3-trichloropro- pane and 1-methyl-2-pyrrolidone listed in REACH with GC-MS is established. The conditions of chromatography and pretreat- ment of sample are optimized as follows： ultrasonica extraction with acetone and filtering with organic phase membrane of 0.45 μm. The method is linear with the range of the study herein with the correlation coefficient above 0.994. This method features easy, accurate and sensitive with RSD less than 10% and detection limit much less than 0.1% of the limited requirements of REACH.
