采用 5 %OV -10 1/GasChromQ(15 0～ 180 μm)色谱柱 ,邻苯二甲酸二戊酯为内标物 ,对毒·唑磷乳油有效成分毒死蜱、三唑磷含量进行气相色谱分析 ,毒死蜱、三唑磷变异系数分别为 1.6 3 %和 0 .6 7% ,线性相关系数分别为 0 .990 7和 1.0 0 6 9;回收率分别为 99.1%～ 10 0 .1%和 99.6 %～ 99.7%。
The contents of chlorpyrifos and triazophos in the active constituents of poisonous zooxophos were determined by gas chromatography with 5% OV-10 1 / GasChromQ (15 0-180 μm) column and diamyl phthalate as internal standard. The coefficient of variation of chlorpyrifos and triazophos were 1.6 3% and 0.67%, respectively, and the linear correlation coefficients were 0.990 7 and 1.0 0 6 9 respectively. The recoveries were 99.1% -101.0% and 99.6% 99.7%.
