Effects of Column Temperature (SI-50 4D)

Please use this column with suppressor type ion chromatography system.

The effects of column temperature on analysis of seven general inorganic anions using IC SI-50 4D, a column for anions analysis, were studied. Effects of temperature on elution positions of each ion was found to be negligible. However, separation performance gradually decreased above 40 ℃. Therefore, it is recommended to set the column temperature between 30 and 35 ℃.
