Analysis of Oxyhalides and Anions (SI-52 4E)

High resolution ion chromatography column, IC
SI-52 4E was used for the quantification of several oxyhalides and inorganic ions. Ethylenediamine (0.1% v/v of 50 mg/mL) is added to the water samples to prevent HCl production from the reaction between residual chloride and chlorous acid.
