Analysis of Bifenthrin and its Enantiomer Using High Performance Liquid Chromatography

Abstract:

Using the high performance liquid chromatography (HPLC) method, bifenthrin isomers can be split at a polysaccharide derivatives chiral stationary phase column, and two well distinguished peaks of bifenthrin isomers are obtained. The effects of mobile phase ratios, temperatures, and detection wavelengths on the separation results are discussed. The optimal chromatographic conditions are as follows: the mobile phase ratio is methanol: ammonium acetate salts = 80:20, the column temperature is 35°C, and the wavelength is set as 220 nm. Under the optimal conditions, the resolution of bifenthrin enantiomer can be as large as 3.0.
