本方法采用高效液相色谱法,以甲醇-水溶液作为流动相,用HyPersil BDS C18250mm×4.6mm.10μm柱和紫外检测器,分析乙嘧酚磺酸酯.吡唑醚菌酯30%微乳剂。结果表明:乙嘧酚磺酸酯,吡唑醚菌酯的标准偏差分别为:0.13和0.16;变异系数分别为:0.36%和0.39%;平均回收率分别为:99.1%和99.2%。
The method uses high performance liquid chromatography (HPLC) with methanol-water as the mobile phase, and uses a HyPersil BDS C18 250 mm × 4.6 mm × 10 μm column and an ultraviolet detector to analyze the pyrazole sulfonate and pyraclostrobin 30% microemulsion. The results showed that the standard deviations of pyridoxal and pyraclostrobin were 0.13 and 0.16, respectively. The coefficients of variation were 0.36% and 0.39%, respectively. The average recoveries were 99.1% and 99.2%, respectively.
