Please use this column with suppressor type ion chromatography system.
Iodide ion was analyzed using IC SI-90 4E (a column for anion analysis). Iodide ion elutes after sulfate ion when analyzed at ambient temperature (25 °C), but it elutes before sulfate ion when analyzed at 50 °C. As shown here, the elution timing of iodide ion changes considerably compared to other anions, it is important to control the column temperature during the analysis.
