✦ Synopsis

A new approach for the determmatlon of ethanol m beverages IS presented The hydrogen peronde generated m the enzymatlcally catalyzed ondatlon of ethanol 1s measured by the lummol chemdurmnescence reaction usmg potassium hexacyanoferrate(II1) as a catalyst Alcohol ondase IS Immobhd on ammopropyl glass beads packed m a glass column The chemdummescence measurement 1s made usmg an optax fiber to transport the hunmescence from the flow cell to the detector m conJunctIon wth a flow system Thus assay system responds hnearly m the ethanol concentration range 3 X 10m6-7 5 X low4 M wth a precmlon of 2 4% and an analysis hme of 15 mm
