33%苯噻酰·异丙·苄可湿性粉剂的高效液相色谱分析

Analysis of 33% Mefenacet·Metolachlor·Bensulfuron Methyl Wet Powder by HPLC

采用甲醇 水 (HAC)为流动相体系 ,C18反相柱为分析柱 ,紫外检测器进行检测的反相高效液相色谱法同时测定 33%苯噻酰·异丙·苄可湿性粉剂中三个有效成分的含量。该方法测定苯噻酰草胺、异丙甲草胺和苄嘧磺隆的标准偏差分别为 0 94、0 0 70、0 0 2 9,变异系数分别为 0 37%、1 4 4 %、0 85 % ,平均回收率分别 10 0 3%、99 7%、99 2 % ,线性相关系数分别为 0 99978,0 99992 ,0 99994。

Mefenacet·Metolachlor·Bensulfuron Methyl wet powder (WP) was analyzed by HPLC using UV detection and methanol-water(HAC)as fluid phase and ODS-C 18 reverse phase column.The linear relationships, the standard deviation, and the variation coefficients of this method are very good.The standard deviations of Mefenacet, Metolachlor, and bensuulfuron methyl are 0.94,0.070,0.029.The variation coefficeients are 0.37%,1.44%,0.85%.The average recovery rates are 100.3%,99.7%,99.2%.The linear relationships are 0.99978,0.99992,0.99994.
