Please use this column with suppressor type ion chromatography system.
IC SI-36 4D is a column for anion analysis using potassium hydroxide aqueous solution as eluent. With columns using carbonate aqueous solution as eluent, sulfate ion elutes after phosphate ion. But using SI-36 4D, sulfate ion is eluted faster than monovalent bromide ions. In the case of columns using carbonate aqueous solution as eluent. Adding some organic solvent to the eluent is necessary to separating sulfite and sulfate ions. On the other hand, SI-36 4D does not require organic solvent to achive the separating. Under gradient conditions, phosphate ions are eluted within 15 minutes, analysis time is shortened.
