Description	Práce popisuje metodu stanovení chlorfenolů ve varní vodě a pivu. Pro extrakci a zakoncentrování analytů byla využita technika extrakce na pevné fázi (SPE). Poté byly chlorfenoly derivatizovány anhydridem kyseliny octové a stanoveny na plynovém chromatografu s detektorem elektronového záchytu. V práci byly porovnány SPE kolonky LiChrolut EN (ethylvinylbenzen–divinylbenzen kopolymer s extrémně velkým specifickým povrchem) a LiChrolut RP-18. Kromě toho byl zkoumán vliv různého objemu elučního činidla na výtěžnost chlorfenolů. V práci jsou dále popsány pracovní charakteristiky optimalizované metody. (cs) A method for the determination of chlorinated phenols in brewing liquor and beer is described. Solid phase extraction technique for the sample preconcentration was used. Then the analytes were derivatized and determined by gas chromatographic analysis coupled with electron capture detector. SPE columns LiChrolut EN (ethyl vinyl benzene – divinyl benzene copolymer with an extremely large specific surface) and LiChrolut RP-18 were tested. The dependences of recovery on the eluent volume were investigated. Validated parameters of the optimized method for the determination of chlorinated phenols in brewing liquor and beer are shown in this work.
