By using lgepal CA 630 and didecyl phthalate as stationary phases on Chromosorb G‐AW, DMCS, and a mixture of GE‐SF 96 and Embaphase as stationary phases on Chromosorb W, gas chromatographic columns were obtained which were used for the analysis of volatile sulphur compounds. Applying a Melpar Flame Photometric detector, minute traces of hydrogen sulphide and alkane thiols in beer could be determined quantitatively. Threshold values of perception of different thiols and organic sulphides were also determined in beer. As levels of these values were in the same range as the sensitivity limit of the gas chromatographic system, organoleptic and gas chromatographic results could be compared.
