Cephapirin confirmation

Liquid chromatography-thermospray-mass spectrometry has been successfully applied for the detection/ confirmation of nicarbazin residues in chicken tissues using negative-ion detection in SIM mode. Liquid chromatography-thermospray-mass spectrometry in SIM mode has also been used for the quantification of residues of moxidectin in cattle tissues and fat, ° and nitroxynil, rafoxanide, and levamisole in muscle. Confirmatory methods based on LC-TSP-MS have been further reported for the determination of penicillin G, cephapirin, and various penicillin derivatives " in mUk. Comparative evaluation of the confirmatory efficiency of LC-TSP-MS and LC-TSP-MS-MS in the assay of maduramycin in chicken fat showed the former approach to be marginally appropriate, whereas the latter is highly efficient. Tandem LC-MS-MS has also been successfully applied in the analysis of residues of chloramphenicol in milk and fish. ... [Pg.548]

LC-PB-MS has been investigated as a potential confirmatory method for the determination of malachite green in incurred catfish tissue, " and cephapirin, furo-semide, and methylene blue in milk, kidney, and muscle tissue, respectively. LC-PB-MS has also been investigated for the analysis of ivermectin residues in bovine hver and milk. The specificity required for regulatory confirmation was obtained by monitoring the molecular... [Pg.919]
