Popis: The authors in a previous work had reported on the determination of seven quinolone antibiotics in gilthead sea bream using liquid chromatography–tandem mass spectrometry, which is a rather expensive and not always available analytical technique. In this work, photodiode array detection is used, so that no sophisticated instrumentation is necessary, following the same sample preparation procedure. A high performance liquid chromatography method for the determination of seven quinolone antibiotics in fish feed and gilthead sea bream (Sparus aurata L.) tissue was developed and validated in terms of selectivity, linearity, accuracy, precision, sensitivity, robustness, and stability, according to European Decision 2002/657/EC. Ciprofloxacin, danofloxacin, enrofloxacin, sarafloxacin, oxolinic acid, nalidixic acid, and flumequine were separated on a Perfectsil ODS-3 (250 mm × 4 mm, 5 µm) column by gradient elution, using a mobile phase consisting of 0.1% trifluoroacetic acid (pH = 1), acetonitrile, and methanol...
