Abstract:A method for continuous determination of imidacloprid and paclobutrazol is described by high performance liquid chromatography. A baseline resolution of imidacloprid and paclobutrazol with impurities was achieved on Bondapak C_(18) column within 12 min by using methanol-water system (70∶30 by voiume) as a mobile phase at flow rate of 1ml/min, and the eluate was monitored at λ=254nm. Imidacloprid and paclobutrazol in the liner range of 0.8~15.0mg/L and 1.5~25mg/L has a good linearity with its high (r=0.9995 ...
Key words:imidacloprid; paclobutrazol; high performance liquid chromatography; continuous determination
