Shodex IC SI-series for carbonate eluent (Na2Co3/NaHCo3) 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. Typical applications include analysis of general inorganic ions and oxyhalides.
Features
- Suitable for anion analysis for suppressor methods with carbonate eluent
- Quaternary ammonium functional groups
- Polyvinyl alcohol particles
- PEEK housing
- 3.5 µm, 5 µm or 9 µm particle size
- Typically used for general inorganic ions and oxyhalides applications
