DESCRIPTION
ISO 6557-1:1986
The method uses the molecular fluorescence spectrometry for the determination of the combined ascorbic and dehydroascorbic acid content. It consists in transforming ascorbic acid into dehydrascorbic acid using activated charcoal, and reacting this with o-phenylendiamine (OPDA).
