IC SI-50 4E, 4.0 x 250 mm, HPLC column (Ion Chromatography)

The Shodex IC SI-50 ion chromatography column 250x4.0mm, 5µm, based on polyvinyl alcohol particles with quaternary ammonium groups. Shodex IC SI-50 offers high efficiency in suppressed anion chromatography and separates inorganic anions as well as selected organic acids. Selectivity is designed so that the carbonate system peak minimally affects typical target ions.

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.
