Simultaneous Determination of 20 Sulfonamide Residues in Pork by Filter-Based Solid-Phase Extraction Cleanup and UHPLC–MS/MS
To enable rapid and accurate determination of sulfonamide residues in animal-derived foods, a method was developed for the simultaneous analysis of 20 sulfonamides by ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) combined with a FaVEx one-step cleanup column, using pork as a repres...
