Simultaneous Analysis of Common Oxyhalides and Anions (SI-37 4D)

Please use this column with suppressor type ion chromatography system.

IC SI-37 4D is a column for anion analysis using potassium hydroxide aqueous solution as eluent. It can separates common oxyhalides and anions under isocratic conditions. With SI-37 4D, sulfate ion eluetes before monovalent chlorate ion while with other carbonate columns, sulfate ion eluetes after phosphate ion.
