以甲醇-乙腈-水(体积比30∶30∶40)为流动相,使用Hypersil ODS不锈钢柱,在225 nm条件下使用紫外检测器,对28%丙环.咪鲜胺水乳剂进行高效液相色谱分离和测定,外标法定量。该测定方法下各有效成分回收率分别为:丙环唑99.06%～100.84%,咪鲜胺99.83%～100.04%;标准偏差:丙环唑为0.025 9,咪鲜胺为0.095 0;变异系数:丙环唑为0.315%,咪鲜胺为0.465%;线性相关系数:丙环唑为0.999 99(同分异构体1)或0.999 80(同分异构体2),咪鲜胺为0.999 72。该方法快速、准确、可靠。
The mobile phase consisted of methanol-acetonitrile-water (30:30:40 by volume), using a Hypersil ODS stainless steel column with a UV detector at 225 nm for a 28% Chromatography and determination, external standard method. The recoveries of the active ingredients in this method were 99.06% ~ 100.84% for propiconazole and 99.83% ~ 100.04% for prochloraz, respectively. The standard deviation was 0.025 9 for propiconazole and 0.095 0 for prochloraz. Coefficient of variation 0.315% for propiconazole and 0.465% for prochloraz; linear correlation coefficients: propiconazole 0.999 99 (isomer 1) or 0.999 80 (isomer 2), prochloraz was 0.999 72 . The method is fast, accurate and reliable.
