40%烯酰·霜脲氰悬浮剂高效液相色谱分析

Analysis of Dimethomorph+Cymoxanil 40% SC by HPLC

采用高效液相色谱法分析烯酰吗啉.霜脲氰复配制剂,使用C18反相柱和紫外可变波长检测器,以甲醇+水为流动相,用外标法对有效成分进行分析和定量。烯酰吗啉和霜脲氰标准偏差分别为0.06和0.05,变异系数分别为0.24%和0.32%,平均回收率分别为100.0%和98.8%。

A method was developed for the determination of dimethomorph＋cymoxanil 40% SC by HPLC on C18 column with UV-absorbance detector,and mobilephase of methanol-water.The results showed that the standard deviations,variation coefficients and average recoveries of dimethomorph and cymoxanil were 0.06,0.24%,100.0% and 0.05,0.32%,98.8%,respectively.
