摘  要:
建立了15%唑虫酰胺乳油的高效液相色谱定量分析法。采用外标法,以甲醇+水(体积比80∶20)为流动相,使用ODS-C18不锈钢柱,在检测波长为240 nm、流速为1.0 mL/min的条件下,对15%唑虫酰胺乳油进行定量分析。其线性相关系数为0.9999,标准偏差为0.0418,变异系数为0.27%,平均回收率为99.87%。该方法操作简便、快速、准确,分离效果好,准确度和精确度均能达到定量分析要求。

摘  要:
A HPLC method was developed for quantitative determination of tolfenpyrad 15% EC,using ODS-C18 column with UV detector at 240 nm.The mobile phase consisted of methanol and water with a volume ratio of 80∶20 and a flow rate of 1.0 mL/min.The linear correlation coefficient of the analytical method was 0.999 9,the standard deviation was 0.041 8,the coefficient of variation was 0.27%,and the average recovery was 99.87%.The method had such advantages as simpleness,convenience,accuracy and good-seperation.
