Abstract
L'invention concerne un procédé et une pile électrochimique qui permettent d'effectuer la détermination quantitative des alcools. L'alcool à analyser arrive directement ou indirectement au niveau de l'anode, où il est oxydé. Un agent oxydant ou un gaz inerte est amené à la cathode. La tension ou le courant généré dans la pile sont utilisés comme mesure pour déterminer la concentration en alcool.
