Rapid Analysis of Oxyhalides and Anions (SI-35 4D) (2)

Please use this column with suppressor type ion chromatography system.

Oxyhalides and standard anions were analyzed simultaneously by IC SI-35 4D, a column for suppressor anion analysis. Under this analytical conditions, elution time of each anion was longer than the conditions of “Rapid Analysis of Oxyhalides and Anions using SI-35 4D (1)”, but the resolution of each anion was improved.
