Anion Standards (20) (Simultaneous Analysis of HS^-, SO₃^2-, SO₄^2- and S₂O₃^2-)

Please use this column with suppressor type ion chromatography system.

Anion standards were analyzed using IC SI-90 4E (a column for anions analysis). HS^- is difficult to detect by conductivity. To separate and detect the above-mentioned anions, UV and CD detector are connected in series.
