采用反相高效液相色谱法 ,使用C18柱和紫外检测器 ,以甲醇 +水为流动相 ,在 2 2 0nm波长下 ,对腈菌唑·咪鲜胺乳油中腈菌唑和咪鲜胺进行定量测定。结果其线性关系分别为 0 .9991和 1.0 0 0 0 ,变异系数均为 0 .5 6% ,平均回收率分别为 10 0 .4%和 99.2 %。
The myclobutanil and prochloraz in myclobutanil and prochloraz were separated by reversed-phase high-performance liquid chromatography with C18 column and UV detector using methanol + water as the mobile phase at a wavelength of 220 nm Quantitative determination. The linear relationship was 0.9991 and 1.0 0 0 0 respectively. The coefficient of variation was 0.56%. The average recoveries were 100.4% and 99.2% respectively.
