| Abstract: | The Analysis Committee has collaboratively tested both routine headspace gas chromatographic methods and a standardised method for the determination of dimethyl sulphide in beer using the flame photometric and flame ionisation detectors available in the participating laboratories. The mean repeatability value (r95) was 7.8 μg/litre for the concentration range 12–65 μg/litre, and the reproducibility value (R95) showed the relationship R95 = 18.1 + 0.452m μg/litre to the concentration (m). No differences in precision were attributed either to the methods or the types of detectors used. |
