Simple assay for monitoring seven quinolone antibacterials in eggs: extraction with hot water and liquid chromatography coupled to tandem mass spectrometry. Laboratory validation in line with the European Union Commission Decision 657/2002/EC.
A simple and rapid method able to determine residues of seven quinolone antibacterials in whole eggs is presented here. This method is based on the matrix solid-phase dispersion technique with hot water as extractant followed by liquid chromatography-tandem mass spectrometry. After depositing 1.5 g of an egg sample containing the analytes and the analyte… (More)
