The nineteen analyzed antibiotics belong to the 5 most prescribed antibiotic classes in the Czech Republic, namely tetracyclines, macrolides, sulfonamides, fluoroquinolones, and lincosamides. The matrix-matched calibration technique with internal standard addition for each antibiotic group was employed for quantification. Two extractions employing an Oasis HLB cartridge and two injections were needed for each sample due to the different physico-chemical properties of the tested antibiotics. Prior to the extraction on the Oasis HLB SPE cartridge, the samples were adjusted to pH 4.5 and 7.5. The usefulness and versatility of the method was documented by achieving method limits of quantification up to 10 ng L-1 and recoveries >80% for most analytes Pracoviště Mikrobiologický ústav Kontakt Eliška Spurná, eliska.spurna@biomed.cas.cz, Tel.: 241 062 231 Rok sběru 2014
