介绍了胺菊酯·烯丙菊酯·氯菊酯气雾剂中各有效成分质量分析的气相色谱法。该方法使用HP–5毛细管柱和FID检测器,以邻苯二甲酸二丁酯为内标,对样品中的3种有效成分进行同柱分离和测定。结果表明,此方法中烯丙菊酯、胺菊酯、氯菊酯的标准偏差分别为0.00931、0.00577、0.00447;变异系数分别为3.37%、1.01%、2.43%;平均回收率分别为98.66%、99.40%、99.71%;线性相关系数分别为0.9895、0.9921、0.9966。
The gas chromatogram of each active ingredient in tetramethrin · allethrin · permethrin aerosol was introduced. The method uses HP-5 capillary column and FID detector to dibutyl phthalate as an internal standard, the three active ingredients in the sample column separation and determination. The results showed that the standard deviations of allethrin, tetramethrin and permethrin in this method were 0.00931,0.00577 and 0.00447, respectively. The coefficients of variation were 3.37%, 1.01% and 2.43%, respectively. The average recovery rates were 98.66% 99.40% and 99.71%, respectively. The linear correlation coefficients were 0.9895, 0.9921 and 0.9966 respectively.
