Analysis of Oxyhalides and Organic Acids (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.
