25%磺草酮·2甲4氯水剂高效液相色谱分析

HPLC analysis of a sulcotrione·MCPA 25% SL

采用高效液相色谱法分析磺草酮·2甲4氯复配制剂,使用C18反相柱和紫外可变波长检测器,以甲醇+水为流动相,用外标法对有效成分进行分析和定量。磺草酮和2甲4氯标准偏差分别为0.024和0.11,变异系数分别为0.30%和0.63%,平均回收率分别为99.7%和99.6%。

Quantitative analysis was conducted on the active ingredients in a sulcotrione plus MCPA package mix formulation using HPLC with a C 18 reverse phase column, a variable wavelength UV detector, a mobile phase of methanol-water, and an external standard, Standard deviations were 0.024 and 0.11 for sulcotrione and MCPA, respectively, while coefficients of variation were 0,30 and 0.63%, respectively, and average recoveries were 99.7 and 99.6%, respectively.
