Abstract:

A method has been developed for the simultaneous determination of 64 veterinary drugs in aquatic products using ultra-high performance liquid chromatography-quadrupole/electrostatic field orbitrap high-resolution mass spectrometry. The samples were extracted with an acetonitrile/water mixture (80/20, v/v), cleaned up by normal hexane saturated with acetonitrile and primary secondary amine (PSA) adsorbent, quantified with external standard method. The drugs were analyzed in full scan/data dependent mass spectrum 2 (Full MS/ddMS2) Top 1 mode. The calibration curves of the 64 drugs were linear with the correlation coefficients more than 0. 9967. The average recoveries of the 64 analytes ranged from 56.2% to 124.6%, and the relative standard deviations (RSDs) were 1.3%-29.8% in the three kinds of matrixes (fish, shrimp and shell) at three levels. The limits of quantification were 0.2-10 μg/kg. The method is simple, rapid, sensitive, reliable and suitable for the screening of residues in aquatic products.
