A sensitive and selective LC method has been developed for the simultaneous determination of ten sulfonamides in muscles, after pre-column derivatization with fluorescamine. The whole procedure was validated in accordance with the Commission Decision 2002/657/EC. Detections capabilities (CCß) were from 125 µg/kg to 150 µg/kg, and recoveries ranged from 60% to 100% pending from analyte. The results demonstrate that the LC-FLD system is highly effective in analysing trace sulfonamides in muscles.
