IC SI-36 4D, 4.0 x 150 mm, HPLC column (Ion Chromatography)

The Shodex IC SI-36 4D ion chromatography column 150x4.0mm, 3.5µm, is designed for anion chromatography with hydroxide eluents and suppression. The Shodex IC SI-36 4D enables the separation of common anions including sulphite and sulphate under KOH conditions. The phase is suitable for complex water and process samples where a hydroxide-based gradient elution is required.

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.
