Abstract
A method for the determination of dimethyl sulphide in beer by headspace gas chromatography has been collaboratively tested within ten laboratories of one brewing group at 3 levels from 19.8 to 52.4 μg/litre. The repeatability values (r35 were found to be independent of concentration, but a strong linear relationship was found between the mean values (m) and the reproducibility value (R35). The precision data can be summarised as r35 = 3.3 μg/litre, R35 = 3.66 + 0.168 μg/litre.Keywords
