Abstract: The separation and quantitation of phosphorous oxoanions have been investigated by non-suppressed ion chromatogra- phy (IC) with conductometric detection using a modified gluconate-borate buffer as eluent. Hypophosphite being coeluted with the injection peak, its previous oxidation into phosphate is necessary. The method was applied to the determination of hypophos- phite and phosphate in several pharmaceuticals
