采用反相高效液相色谱法 ,以C1 8为色谱柱 ,用甲醇 +乙腈 +0 .0 35mol/LKH2 PO4 水溶液=2 4 +11+6 5 (体积比 )作为流动相 ,在 2 4 0nm波长下同时测定多菌灵和三环唑的含量。本方法中多菌灵和三环唑的标准偏差分别为 0 .0 4 12、0 .0 4 4 9;变异系数分别为 0 .4 0 5 %、0 .4 39% ;回收率分别为 99.4 %、99.8%
Using reversed-phase high performance liquid chromatography (HPLC) with C1 8 as the mobile phase and methanol + acetonitrile +0.035 mol / L KH2PO4 aqueous solution = 24 +11 +65 The simultaneous determination of carbendazim and tricyclazole content. The standard deviations of carbendazim and tricyclazole in this method were 0. 0412,0. 04 4 9 respectively. The coefficients of variation were 0.45% and 0.399%, respectively. The recoveries were 99.4% %, 99.8%
