丁醚脲10%乳油高效液相色谱分析

HPLC Analysis Research of 10% Bifenthrin Spirotetramat EC

本文采用高效液相色谱法,以甲醇+水溶液为流动相,使用Hypersil ODS2 C185μm为填料的不锈钢柱和紫外波长检测器,检测波长230nm,对丁醚脲10%乳油进行的定量分析。结果表明,方法的标准偏差分别为0.050,变异系数为0.492%,平均回收率为99.62%,线性相关系数为0.999。

The essay use HPLC to analysis 10% Diafenthiuron EC,use acetonitrile and 0.1acetic acid as mobile phase, Hypersil ODS2 C18 μ5m as stainless steel pillar stuffed,UV wavelength detector, and wavelength detect as 230nm. The result shows this method standard deviation as 0.050, coefficient of variation as 0.492% ,1.051% , average recovery rate as 99.62% , linear correlation conefficient as 0.999.
