Abstract


A catalytic fuel cell has been employed to check ethanol content in several samples of commercial wines, beers and hard liquor drinks. Two other conventional biosensors, based on catalase or alcohol oxidase enzyme, were also used, to the same purpose, on the same samples. Data obtained by three sensor methods have been compared and correlated. Lastly t-test and F-test were applied.
