Development of a High Performance Ion Chromatographic (HPIC) Method for the Determination of Sodium Metabisulfite in Parenteral Formulations

Abstract

A high performance ion chromatographic (HPIC) method for the determination of sodium metabisulfite (a pharmaceutical antioxidant) in injectable formulations is described. The method is selective for both the sulfite and sulfate ions with a minimum of sample preparation.
