Abstract

The concentration of a C.sub.1 to C.sub.4 alcohol in an essentially water immiscible organic system is accurately determined by a simple and quick process. A sample of the water immiscible organic system containing less than about 0.01% (W/V) of the alcohol is contacted with an aqueous layer of alcohol oxidase immobilized on an electrode for measuring dissolved oxygen content. Ethanol in the water immiscible organic system partitions into the aqueous layer where alcohol oxidase catalyzes oxidation of the alcohol. Oxygen consumed during the oxidation is measured by the electrode, and the concentration of alcohol determined therefrom. To obtain less than about 0.01% alcohol in the sample, the sample may be diluted with the water immiscible organic system.
