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。
Determination of imidacloprid and pyridaben in binary mixed pyrida WP by high performance liquid chromatography. The column was μBondapakC18 column (3.9 mm id × 300 mm) with a mobile phase of acetonitrile-methanol-water (volume ratio of 60:10:30) with a diode array detector at a wavelength of 2 40 nm, can be satisfied with the separation effect.
