- Scope
- This standard specifies a gas chromatographic method for ethanol, in which higher alcohols (propan-l-ol, butan-l-ol, butan-2-ol, 2-methylpropan-l-ol (isobutanol), 2-methylbutan-l-ot, and 3-methylbutan-l-ol) up to 2,5 % (m/m), methanol up to 3 % (m/m) and other volatile impurities, especially ethyl-ethanoate (ethyl acetate), ethanal (acetic aldehyde) and 1,1-diethoxyethane (acetal) in the range up to 2 % (m/m) are determined. Due to possible interferences the method is not applicable to denatured ethanol samples. NOTE For the purposes of this document, the term "% (m/m)" is used to represent the mass fraction of a material.
