|Abstract:||By this Letter to the Editor we want to inform the readers of RCM about the on-going works for the measurement of oxygen-18 content of ethanol using commercially available pyrolysis systems. The measurement of this isotope ratio seems very promising as a probe for the authentication of alcoholic beverages. In this letter we report data about the comparability of results produced in a peer testing exercise that involved 12 laboratories in Europe and Japan and that is a prelude to an international collaborative study to validate a protocol for the measurement of 18 O/16 O ratio of ethanol. These data are interesting for further works and harmonisation of methods and measurements for control of authenticity with such techniques.|
