Using of faster gas chromatography is one way how the requirement of quick getting of results could be solved. Silica capillary columns with new size of internal diameter - 0.18 mm - are now available on the market. This study is focussed on applications of these narrow bore columns and their comparisons with usually applied columns with 0.32 mm of internal diameter for determination of high volatile beer flavours. All of these compounds were extracted from beer matrix by headspace method. Flame ionization detector was used for the detection of these analytes.Using of faster gas chromatography is one way how the requirement of quick getting of results...

In this part, new findings concerning the real data of the content of aromatic alcohols in Czech beers are summarized. The content of aromatic alcohols in draught, lager and non alcoholic beers was studied. In the case of non alcoholic beers, the first information concerning the influence of technological process on the changes of the content of these sensory active compounds was acquired.In this part, new findings concerning the real data of the content of aromatic alcohols in Czech beers are summarized.
