Using HPLC reversedphasecolumn(ODS-C18), methanol:water (50:50) as mobile phase, the contents of two active ingredients of Seed-coating of Kefu were determined successfully.
Using reversed-phase chromatographic column and diode array detector, content of imidacloprid and pyridaben in their water soluble powder was measured with high effective liquid chromatography.
采用高效液相色谱法，使用反相色谱柱和二极管阵列检测器测定吡·哒可湿性粉剂中吡虫啉和哒螨灵的含量。
