摘要
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 quantitative determination of quinaiphos and carbosulfan 16% EC were analyzed by HPLC. Operating conditions were C18 column, methanol and water （90：10, by vol） as mobile phase, UV-315 nm spectrum length within 3.8 min and UV-280 nm during 3.8 to 7.5 min. The results showed that the standard deviations, coefficient of variation, average of recovery and linear correlation were 0.215, 0.212%, 95.98 to 101.42% and 0.9999 respectively for quinaiphos, 0.172, 0.171%, 96.04 to 101.87% and 0.9998 respectively for carbosulfan.
