氟丙菊酯·阿维菌素水乳剂高效液相色谱分析方法研究

Analytical Method of Afidopyropen and Abamectin EW by HPLC

本文采用高效液相色谱法,以乙腈+磷酸溶液为流动相,使用以ZORBAX SB-Aq、5μm为填料的不锈钢柱和二极管阵列检测器.在245nm波下对氟丙菊酯·阿维菌素水乳剂进行分离和定量分析。结果表明,该分析方法中氟丙菊酯线性相关系数为0.999 9,标准偏差为0.02,变异系数为0.84%,平均回收率为99.76%;阿维菌素的线性相关系数为1.000 0,标准偏差为0.03,变异系数为0.22%,平均回收率为99.52%。

A method for separation and quantitative analysis of acrinathrin and abamectin EW by HPLC with acetonitrile and H_3PO_4 solution as mobile phase,ZORBAX SB-A_q column and DAD at 245 nm wavelength was described.The results showed that the linear correlation coefficient of acrinathrin was 0.999 9,the standard deviation was 0.02,the variation coefficient was0.84%,the average recovery was 99.76%;the linear correlation coefficient of abamectin was1.000 0,the standard deviation was 0.01,the variation coefficient was 0.22%,the average recovery was 99.52%.
