Use of organic buffers to reduce dehydroascorbic acid interference in analytical methods

Abstract From the Canadian patent

Abstract of the Disclosure, The interference of dehydroascorbic acid an, oxidation product of ascorbic acid in analytical, methods is reduced with the use of certain nitrogencontaining organic buffers. Dehydroascorbic acid tends to cause premature reduction of reducible compounds which are used to provide detectable species in the presence of an analyte. These organic buffers, as opposed to inorganic buffers, prevent premature reduction of the reducible compounds. An analytical method can be carried out in solution or in a dry analytical element.
