AbstractA liquid chromatography-tandem mass spectrometry (LC/ESI/MS/MS) method was developed and validated for the determination of ten sulfonamide antibiotic residues in raw shrimp meat: sulfadimethoxine, sulfachloropyridizine, sulfamethoxypyridizine, sulfamethazine, sulfamethizole, sulfamerazine, sulfathiazole, sulfamethoxazole, sulfadiazine, sulfapyridine. The procedure involves the extraction of homogenized sample into acetonitrile and diluted with mobile phase. The analysis was carried out using ODS-EP 5 micron, 100×2.1mm column and mobile phase consists of 0.1% formic acid (A) and acetonitrile (B) in gradient mode at a flow rate of 0.5 mL/min. The final extracts were analyzed by the sensitive and selective LC/ESI/MS/MS operating in positive ion multiple reactions monitoring (MRM) mode.
