Product Description
The Shodex IC YK-421 ion chromatography column 125x4.6mm, 5µm, uses carboxyl-functionalised silica as a weak cation exchanger. Shodex IC YK-421 is intended for non-suppressed analysis of mono- and divalent cations as well as alkylamines. The silica-based material provides selectivity different from the polymeric YS-50 and is used in routine, pharmaceutical and water analyses.
Features and Benefits
- Anion and cation exchangers
- Suppressed and non-suppressed IC
- Fast and highly sensitive versions
- Special selectivities for oxyhalides
- Robust polymer and silica packings
Additional Information
The IC Series primarily consists of polymer-based ion exchangers with polyvinyl alcohol or polymethacrylate backbones, as well as YK-421, a silica-based cation exchange phase. Quaternary ammonium groups provide strong anion exchange selectivity, while carboxyl groups are used for cation separation. Particle size, exchange capacity, and surface chemistry are optimized for carbonate, hydroxide, or non-suppressed eluent systems, depending on the column.
