建立了在同一色谱条件下测定混剂中甲基硫菌灵和咪鲜胺含量的方法。采用Inertsil ODS-3柱分离,以甲醇-水(体积比79∶21)为流动相,在230nm紫外检测波长下,经保留时间定性确证,峰面积外标法进行定量分析。结果表明:甲基硫菌灵与咪鲜胺的线性相关系数分别为0.9997和0.9999;变异系数分别为0.24%和0.48%;平均回收率分别为99.35%和99.33%。
A method was established for the determination of thiophanate-methyl and prochloraz in the mixture under the same chromatographic conditions. The separation was performed on an Inertsil ODS-3 column. The mobile phase was methanol-water (79:21 by volume) and was identified by the retention time at 230 nm. The peak area was determined by external standard method. The results showed that the linear correlation coefficients of thiophanate methyl and prochloraz were 0.9997 and 0.9999, respectively. The coefficients of variation were 0.24% and 0.48%, respectively. The average recoveries were 99.35% and 99.33% respectively.
