摘要
[目的]建立50%嘧菌酯水分散粒剂高效液相色谱分析方法。[方法]以乙腈-水-甲酸为流动相,使用ODS-C18反相柱,在225 nm检测波长下,对样品进行分离检测。[结果]嘧菌酯的标准偏差为0.1877,变异系数为0.37%,平均回收率为100.2%,线性相关系数为0.9998。[结论]该方法操作简便快捷,准确度和精密度高,线性相关性好。
[Aims] A HPLC method for analysing 50% azoxystrobin dispersible granule was established. [Methods] The sample was separated and analyzed quantitatively on ODS-C18 reversed-phase chromatography column and UV detector at 225 nm, using acetonitrile : water : methanol as the mobile phase. [Results] The results showed that the standard deviation of azoxystrobin was 0.187 7, the variation coefficient was 0.37%, the average recovery rate was 100.2%, the linear correlation coefficient was 0.999 8. [Conclusions] The method was simple, rapid and accurate, and had good linear correlation.
