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 \u2013 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." .
