目的使用气相色谱法分析测定8%乐安居乳油有效成分含量了解其方法是否更有效。方法采用Agilent HP-1色谱柱,用ECD检测器对8%乐安居乳油进行了定量分析,建立了8%乐安居乳油中氯菊酯含量的气相检测方法。结果本方法的变异系数为0.005 74,标准偏差为0.047 2,平均回收率为96.58%,线性系数为0.999 5。结论该方法方便、快速、准确、重现性好,可作为测定8%乐安居乳油有效成分的有效方法。
Purpose To determine if the method is more effective by measuring the active ingredient content of 8% Leanju EC using gas chromatography. Methods A gas chromatographic method was developed for the determination of permethrin content in 8% leonuride EC using Agilent HP-1 column with ECD detector. Results The coefficient of variation of this method was 0.005 74, the standard deviation was 0.047 2, the average recovery was 96.58% and the linearity coefficient was 0.999 5. Conclusion The method is convenient, rapid, accurate and reproducible. It can be used as an effective method to determine the active ingredients of 8% Le Anju EC.
