Hydrophobic Anion (SI-90 4E)

Please use this column with suppressor type ion chromatography system.

Hydrophobic anions were analyzed using IC SI-90 4E (a column for anions analysis). If the acetone is added to eluent, hydrophobic anions are be eluted early. Moreover, the separation of SO₃^2- and SO₄^2- improves.
