Shodex IC SI-series for hydroxide eluent (KOH/NaOH) ion chromatography columns are suitable for anion analysis with suppressor methods. The columns are made with a polyvinyl alcohol base particle with a quaternary ammonium functional group. IC SI-36 4D provides good separation of sulfate and sulfite ions, and IC SI-37 4D is suitable for high sensitivity analysis of oxyhalides in drinking water.
Features
- Suitable for anion analysis for suppressor methods with NaOH or KOH eluent
- Quaternary ammonium functional groups
- Polyvinyl alcohol particles
- PEEK housing
- 3.5 µm particle size
