AB000487: Determination of Chloride in Multivitamin-Mineral Supplements using Ion Chromatography Be the first to rate this application


This application brief describes a 15 min IC method for the determination of chloride in multivitamin-mineral supplements. The method uses a 2 mm Dionex IonPac AG20/AS20 column set with electrolytically generated potassium hydroxide (KOH) eluent. Using this method, chloride is well resolved from other anions found in the multivitamin samples. The method has a linear calibration over the concentration range from 0.2 to 500 mg/L with r2=1.000 and the method is precise (RSD ≤ 3.0%). The data show this IC-CD method can be used for the determination of chloride in multivitamins.
