Please use this column with suppressor type ion chromatography system.
The relationship between column temperature and retention time of each anion in the anion analysis column IC SI-36 4D is shown below. When the temperature is increased, the elution time of sulfate ions decreased.At 40 ℃ or higher, the elution orders of sulfate ion and bromide ion are reversed. Considering the elution time of carbonate, we recommend a column temperature of 30 ℃ and the use of 25 mM potassium hydroxide aqueous solution as eluent.The relationship between column temperature and retention time of each anion in the anion analysis column SI-36 4D is shown below. The elution behavior with temperature depends on the kind of anion. The higher the temperature, the slower the elution of sulfate ions. At 40 ℃ or higher, the elution orders of sulfate ion and bromide ion are reversed. Considering the elution time of carbonate, column temperature of 30 ℃ is recommended, when using 25 mM potassium hydroxide aqueous solution as eluent.
