| 摘 要： | 本文研究建立了花色蛤中扑草净含量的气质联用测定方法。样品用正己烷提取后，经硅藻土固相萃取柱净化后，注入气质联用仪中进行检测。经弱极性色谱柱分离，EI源离子化，以及sim方式对样品中的扑草净残留量进行定性与定量分析。该方法测定结果的相对标准偏差小于6％（n=6），平均回收率大于74％，线性范围为0．05—1μg／ml，最低检出限为0．00022mg／kg。

| Abstract: | A method for determination of prometryne residue in Color clams by gas chromatography-mass spectrometry （ GC- MS ） was established. The sample solution was injected into GC-MS after extracted by n-hexane and cleaned by the solid phase extract （SPE） tube. The qualitative and quantitative analysis was achieved by EI source, weak polarity capillary column and selected ion mode （S/M）. The RSD of the method was less than 6%（n=6）, and average recovery was more than 74%. The liner range was 0.05-1μg/ml and the detection limit was 0.00022mg/kg. |
