采用气相色谱法,用1m×3mm玻璃柱,内装5%OV17chromosorbWHP(60～80目)固定相,邻苯二甲酸二正戊酯和邻苯二甲酸二乙酯为内标,测定50%乙·敌乳油中有效成分的含量,对硫磷和敌百虫变异系数分别为050%和040%,回收率分别为998%和997%。
Gas chromatography was used to determine the content of 50% B-1 with a 1m × 3mm glass column packed with 5% OV17chromosorbWHP (60-80 mesh) stationary phase, di-n-pentyl phthalate and diethyl phthalate The content of active ingredients in the emulsifiable concentrate of omatosulfan, the coefficients of variation of parathion and trichlorfon were 050% and 040% respectively, and the recoveries were 998% and 997% respectively.
