【摘要】 用高效液相色谱法测定二元混配吡哒可湿性粉剂中的吡虫啉和哒螨灵的质量分数。色谱柱为 μBondapakC1 8柱 (3 .9mm i.d.× 3 0 0 mm) ,流动相为乙腈 -甲醇 -水 (体积比为 60∶ 1 0∶ 3 0 ) ,用二极管阵列检测器 ,检测波长为 2 40 nm,可得到满意的分离效果。更多还原

【Abstract】 A new method for determination of imidacloprid and damanlin by using HPLC was established. It was carried out on a μBondapak C₁8 column （3.9 mm i.d.×300 mm） with ACN\|MeOH\|H\-2O （60∶10∶30,V/V） as eluent and detected at 240 nm using photodiode array detector. The results of imidacloprid and damanlin were 3.71% and 15.65% respectively. The standard deviations for imidacloprid and damanlin were 0.88% and 0.76% respectively.更多还原
