Please use this column with suppressor type ion chromatography system.

High resolution ion chromatography column, IC SI-52 4E was used for the quantification of several oxyhalides and anions. 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.
