IC NI-424, 4.6 x 100 mm, HPLC column (Ion Chromatography)

The Shodex IC NI-424 ion chromatography column 100x4.6mm, 5µm, possesses quaternary ammonium groups on a polyhydroxymethacrylate backbone. Shodex IC NI-424 is designed for non-suppressed anion chromatography and offers higher performance compared with older I-524A materials. Typical applications are inorganic anions including fluoride and phosphate in water, process and food samples.

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.
