原药和制剂中溴氰菊酯的气相色谱分析

Gas Chromatographic Analysis of Delta-methrin in Technicall and Formulated Products

采用ＤＣ－１１＋ＱＦ－１为固定液，邻苯二甲酸二癸酯为内标物，用气相色谱法测定原药和制剂中溴氰菊酯的含量。原药的标准偏差为０．１２，变异系数为０．１２％；２．５％乳油的标准偏差为０．Ｏ３，变异系数为１．３％。

A new method was developed for the determinationof deltamethrin in technical and formulated products by gaschromatography with DC-11+QF-1 as stationary phase anddidecyl phthalate as internal standard. For technical productthe standard deviation was 0.12.the coefficient of variationwas 0.12% for 2.5% EC the standard deviation was 0.03,the coefficient of variation was 1.3%。
