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

Please use this column with a suppressor-type ion chromatography system.

A high-resolution ion chromatography column, IC SI-52 4E was used for the quantification of several oxyhalides and organic acids.
Malic acid and succinic acid will coelute with malonic acid under this condition.
