Overlay of LC-MS2 total ion chromatograms of 35 antimicrobials and 1 beta-lactamase inhibitor (1 = cefepime, 2 = clavulanic acid, 3 = amoxicillin, 4 =cefadroxil, 5 = lincomycin, 6 = ceftazidime, 7 = cefaclor and trimethoprim, 8 = cefalexin and ampicillin, 9 = cefradine and polymyxin B1, 10 = ofloxacin, 11 = norfloxacin, 12 = tetracycline and ciprofloxacin, 13 = azithromycin, 14 = ceftriaxone and cefotaxime, 15 = clindamycin and nitrofurantoin, 16 = bacitracin, 17 = doxycycline, 18 = erythromycin and cefazolin, 19 = clarithromycin, 20 = roxithromycin, 21 = sulfamethoxazole, 22 = penicillin G, rifampicin and cefur- oxime axetil, 22(2) = benzathine (of benzathine penicillin G), 23 =penicillin V, 24 = griseofulvin, 25 = cloxacillin, 26 = gentamicin and neomycin).

Article Snippet: The reference standards of amoxicillin trihydrate, azithromycin, cefaclor, ceftazidime, cefazolin, cefuroxime axetil, clavulanate lithium, clindamycin and cloxacillin sodium were purchased from the European Directorate for the Quality of Medicines (EDQM) (Strasbourg, France).
