摘  要:
采用高效液相色谱法测定20%苯醚甲环唑·烯肟菌胺悬浮剂中的有效成分含量,外标法定量。采用250mm×4.6mm(i.d.)不锈钢柱,内装C18填充物,粒径5μm;以乙腈-水(体积比70∶30)为流动相;流速:1.0mL/min;检测波长:236nm。结果表明:苯醚甲环唑和烯肟菌胺的标准偏差分别为0.075、0.065;变异系数为0.72%、0.62%;平均回收率为98.90%、98.8%。

摘  要:
An reversal phase high performance liquid chromatography method using an external standard was devel-oped for quantitative determination of difenoconazole and SYP-1620 20% SC. Using a C18(250 mm×4.6 mm i.d.) column,acetonitrile-water(70:30,by vol) as mobile phase,and a flow rate of 1.0 mL/min,wavelength of the UV detector was 236 nm. The result showed that the standard deviations of difenoconazole and SYP-1620 were 0.075 and 0.065,the coefficients of variation were 0.72% and 0.62%,respectively,the average recovery were 98.9% and 98.8%.
