| Abstract: | Objective： Ultra High Performance Liquid Chromatography（UPLC） method was determination of chlorpromazine residue in pork. Method： The target analyte was extracted form sample with acetenitrile and determined by UPLA. Chromatographic column： BEH C18 1.7 μm× 50 min×2.1 ram, flow rate： 0.4 mL/min, mobile phase： acetonitrile：ammonium acetate----60：40, column temperature： 40℃, detection wavelength： 254 nm, injection volume：10μL.Result：The detection limit was 15.0pg/kg.The linearity ranged form O to 1.00 mag/ L with the correlation coefficient of 0.9998. The recovery was 87.7% to 101.0%, RSD was 1.2% to 2.6%. Conclusion： The method was suitable for determination of chlorpromazine residue in pork. |
