Please use this column with suppressor type ion chromatography system.

In analysis using IC SI-52 4E, the retention times of some anions are very sensitive to the column temperature. An example is showed in the figure below. Usually bromide (Br^-) and chlorate (ClO₃^-) are usually separated at 45 °C.

3. BrO₃^- (20 mg/L)
4. Cl^- (3 mg/L)
5. NO₂^- (10 mg/L)
6. Br^- (10 mg/L)
