Please use this column with suppressor type ion chromatography system.

The effects of flow rate on analysis of seven general inorganic anions using IC SI-50 4D, a column for anions analysis, were studied. Regardless of the fact that column performance tends to decrease at higher flow rates, baseline separation of each peak was achieved even at the maximum usable flow rate of 1.5 mL/min. Confirming SI-50 4D’s suitability for rapid and high-resolution analyses.
