采用高效液相色谱法,在C18柱上,以甲醇-水(体积比90∶10)为流动相,检测波长0～3.8min315nm,3.8～7.5min 280nm,在7.5min内同时分析16%虫线清乳油中喹硫磷和丁硫克百威两种有效成分的含量。该方法简便、快速、准确,喹硫磷标准偏差为0.215,变异系数为0.212%,回收率为95.98%～101.42%,线性相关系数0.9999;丁硫克百威标准偏差为0.172,变异系数为0.171%,回收率为96.04%～101.87%,线性相关系数0.9998。
The mobile phase was methanol-water (volume ratio 90:10). The detection wavelength was 3.8 ~ 7.5min and 280nm at 3.8 ~ 7.5min. On the C18 column, the detection wavelength was 16% Contents of the two active ingredients of quetiapine and carbosulfan in Qing EC. The method was simple, rapid and accurate. The standard deviation of quetiapine was 0.215, the coefficient of variation was 0.212%, the recovery was 95.98% ~ 101.42%, the linear correlation coefficient was 0.9999. The standard deviation of butylthiocarb was 0.172 and the coefficient of variation was 0.171 %, The recovery rate was 96.04% ~ 101.87%, the linear correlation coefficient was 0.9998.
