采用高效液相色谱法对苯噻草胺和吡嘧磺隆混合制剂作定量分析,变异系数分别为0.99%和1.08%;标准偏差分别为0.2420和0.0114;回收率分别为99.21%～100.21%和99.52%～100.16%。
The quantitative analysis of the mixture of mefenacet and pyrazosulfuron ethyl with high performance liquid chromatography showed that the coefficients of variation were 0.99% and 1.08%, respectively. The standard deviations were 0.2420 and 0.0114, respectively. The recoveries were between 99.21% and 100.21% 99.52% ~ 100.16%.
