10%氟苯虫酰胺悬浮剂的高效液相色谱分析

Analysis of Flubendiamide 10% SC by HPLC

[目的]建立高效液相色谱法测定氟苯虫酰胺悬浮剂中有效成分含量法分析方法。[方法]采用C_(18)色谱柱,以甲醇-水(0.1%冰醋酸水溶液)为流动相,在波长235 nm进行测定。[结果]方法的线性相关系数为0.9992,平均回收率为102.31%,标准偏差为0.033,变异系数为0.33%。[结论]该方法操作简便,线性关系良好,具有较高的精密度和准确度,可以用于氟苯虫酰胺悬浮剂的产品质量检验。

[Aims] A HPLC method for determination of flubendiamide SC was established. [Methods] The chromatographic conditions were systematically investigated with C_（18） column as the stationary phase, the mixture of methanol and acetic acid as the mobile phase at 235 nm. [Results] The linear correlation coefficient was 0.9992. The average recovery rate was 102.31%. In addition, the standard deviation was 0.033, the variation coefficient was 0.33%.[Conclusions] The method has the advantage of simple, good linear relationship, high precision and accuracy, which is suitable for quantitative analysis of flubendiamide SC.
