摘要
采用高效液相色谱法测定乙霉威原药含量。以甲醇和水为流动相,采用Nova-Pak C_(18)不锈钢柱,检测波长为245nm,以外标法对乙霉威原药进行定量分析。结果表明,乙霉威的标准曲线线性回归系数为0.9949,标准偏差为0.16,变异系数为0.17%,平均回收率为100.02%。该方法简单、快速,且准确度高,重现性好,具有良好的线性关系。
A HPLC method was developed for the determination of diethofencarb TC.The HPLC conditions were as follows:Nova-Pak C18 column,mobile phase of methanol and water,and detection wavelength of 245 nm.The results showed that the linear correlation coefficient of the method was 0.9949,the standard deviation was 0.16,the variation coefficient was 0.17%,and the average recovery was 100.02%,respectively.The method is simple,rapid,accurate,reproducible and linear.
