Development of Multiresidue Methods to Determine and Confirm Sulfonamides in Edible Tissues of Aquacultured Species


To develop analytical chemical methods to determine and confirm sulfonamide (SA) residues at the 1-10 ng/g level in edible tissues of aquacultured species. Technologies used will include liquid chromatography (LC) with post column derivatization and fluorescence detection for the determinative procedure and liquid chromatography with atmospheric pressure chemical ionization mass spectrometry LC-APCI/MS for the confirmatory procedure.
