Please use this column with suppressor type ion chromatography system.
The concentration of sodium carbonate (Na2CO3) in eluent influences the retention of some anions when analyzed by IC SI-90 4E (a column for anions analysis). The relationship between sodium carbonate concentration and anions' retention time is shown below. Elution volumes of anions from fluoride to nitrate are not influenced considerably by the change in sodium carbonate concentration. While retention volumes of later eluting anions (phosphate to iodide ion) are shorten by increasing the sodium carbonate concentration.
