The present study aims at development of method for simultaneous estimation of chloride and citrate in oral rehydration salt (ORS) by ion chromatography and its validation. The estimation was carried out with a step change gradient mode by altering concentrations of NaOH as an eluent, an anion exchange column IonPac AS11 analytical column, guard column AG11 and conductivity detector. The suppressor used was used as ASRS ULTRA. The developed method was validated as per ICH guidelines for various parameters. The method is useful for determining the contents of chloride and citrate in single run from ORS.
