Analysis of Organic Acids and Oxyhalides (SI-52 4E)

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 organic acids. Marlic acid and succinic acid will coelute with malonic acid under this condition.
