Abstract
An alternative chromatographic method based upon a combination of a modified Monnier-Williams procedure and an Ion Chromatography separation and quantitation of sulfite, have been developed. The collected gaseous S02 is oxidized to sulfate with hydrogen peroxide. IC determination was carried out with an anion-exchange polymetacrylate column, borate/gluconate as eluent and conductivity detection. The combined method shows a good detection limit as well as a high chromatographic resolution. It is also applicable to the analysis of several foodstuffs.Keywords
