| Resumen: | This European Standard specifies a gas chromatographic method for ethanol, in which higher alcohols (propan-1-ol, butan-1-ol, butan-2-ol, 2-methylpropan-1-ol (isobutanol), 2 methylbutan 1 ol, and 3 methylbutan 1 ol) from 0,1 % up to 2,5 % (m/m), methanol from 0,1 % up to 3 % (m/m) and other impurities, in the range from 0,1 % up to 2 % (m/m) are determined. Impurities are all the compounds not attributed to the groups of higher alcohols or methanol. Water, if present in the sample, is not included in this analysis, because a signal for water is not visible in the chromatogram. Therefore, if "alcohol content" is called up in a specification, water needs to be considered separately in the calculations. |
