采用反相高效液相色谱外标法,以甲醇-水-冰乙酸作为流动相(体积比为84∶16∶0.1),用C18柱和紫外检测器(230nm)测定了30%苯醚甲环唑·丙环唑乳油的含量。结果表明:方法的标准偏差为0.032、0.082;变异系数为0.21%、0.54%;平均回收率为99.94%、99.71%,线性相关系数为0.9994、0.9988。 Using reversed-phase high performance liquid chromatography with external standard method, methanol-water-glacial acetic acid as mobile phase (volume ratio of 84:16:0.1), C18 column and UV detector (230nm) measured 30% Azole · Propiconazole EC content. The results showed that the standard deviation of the method was 0.032,0.082, the coefficient of variation was 0.21% and 0.54%, the average recovery was 99.94% and 99.71% respectively. The linear correlation coefficients were 0.9994 and 0.9988.
