三唑磷的气相色谱分析

Gas Chromatographic Determination of Triazophas

用３％ＯＶ－１０１的气相色谱填充柱，以邻苯二甲酸双环己酯为内标，用具有氢焰离子化检测器的气相色谱仪对三唑磷原药和乳油进行了定量分析。原药和乳油的标准偏差分别为０３和０２，变异系数分别为０４％和０７％，方法的平均回收率为９９７％。此法操作简便。

A method is described for the determination of triazophos by gas chromatography with FID on 3% OV-101 column using dicychohexyl-O-phthalate as internal standard.The standard deviation for technical and emuliable concentrate were 0.3 and 0.2.The coefficients of variation for technical and emuliable concentrate were 0.4% and 0.7%.The results showed that the average recovery was 99.7%.The method is simple, rapid and accurate .
