Effects of Temperature on Elution Time (SI-90 4E)

Please use this column with suppressor type ion chromatography system.

Effects of temperature on anions' elution time using an IC SI-90 4E (a column for anion analysis) is shown below. Iodide ion eluted earlier as the column temperature increased. The elution time of none of the other anions were influenced considerably by column temperature.
