| Abstract: | A method based on liquid chromatographytandem mass spectrometry （HPLC -MS/MS） was developed for the screening of about 7 kinds of chloramphenicols and nitrofurans in powder of veterinary drug preparation. The analyte was dissolved by water, extracted with ethyl acetate, and cleaned by Oasis HLB solid phase extraction cartridge. Qualitative analysis of the analyte was achieved by HPLC - MS/MS with multiple reaction monitoring （MRM）. The limit of detection and specificity of method was validated through within laboratory test and inter laboratory test respectively. The results showed that the established method was fast, sensitive, specific and quite suitable for identification and qualitative analysis of chloramphenicols and nitrofurans in powder of veterinary drug preparation. |
