Vitamin C is the sum of L ( + ) ascorbic acid and dehydro L ( + ) ascorbic acid.&lt;br /&gt;<br /> <br /> '''Principle'''&lt;br /&gt;<br /> <br /> Vitamin C is extracted from the sample to be analysed using metaphosphoric acid solution. A reducing solution is used to transform dehydro L ( + ) ascorbic acid to L ( + ) ascorbic acid. Total L (+) ascorbic acid content is determined by HPLC with a UV detection at 265 nm.&lt;br /&gt;<br /> <br /> '''Precision data'''&lt;br /&gt;<br /> <br /> * [https://metrofood-wiki.foodcase-services.com/index.php?title=Precision+data+-+vitamin+C link to detailed data]</div>
