Sequential determination of titratable acidity and tartaric acid in wines by flow injection spectrophotometry
A flow injection manifold is proposed for the sequential determination of titratable (total) acidity based on a pseudotitration and of tartaric acid based on the formation of a coloured vanadate complex. The method involves in-line dialysis prior to injection to avoid interference from the sample ba...
