Analytisches Vielschichtelement, Niacinamide enthaltend und Verfahren zur Bestimmung von Ethanol

摘要

A multilayer analytical element has been prepared for accurate and rapid colorimetric determination of ethanol in aqueous specimens using alcohol dehydogenase and an oxidized nicotinamide coenzyme. The element includes two reagent layers beneath a porous spreading layer. The element also contains niacinamide in one or more layers to reduce the interference from alcohols other than ethanol.
