Anion Standards (20) (Simultaneous Analysis of HS-, SO32-, SO42- and S2O32-) (SI-90 4E)

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.
