Please use this column with suppressor type ion chromatography system.
The concentration of potassium hydroxide in eluent influences the retention of each anion when analyzed by IC SI-36 4D (a column for anions analysis). The relationship between potassium hydroxide and anions' retention time is shown below. Basically, the higher the concentration of potassium hydroxide, the faster the elution of anions. The degree of elution is different depending on anions. Especially, retention volumes of phosphate ion, sulfate ion, sulfite ion and carbonate ion are shortened by increasing the concentration of potassium hydroxide.
