RSpak DE-5013 500x50mm Polymer based Preparative Column

The RSpak DE-5013 preparative HPLC column 300x20mm, 12µm, contains polymethacrylate without a bonded alkyl phase. The large-volume format of the RSpak DE-5013 transfers the DE selectivity to particularly high sample amounts and supports scale-up of analytical or smaller preparative methods. The phase is used for purification of polar active ingredients, vitamins, organic acids and other water-soluble target substances.

Features and Benefits

• Silica-free polymer phases
• Reverse-phase and mixed-mode available
• Wide pH range
• Excellent retention of polar compounds
• Robust specialty phases for sugars and acids

Additional Information

RSpak comprises various polymer matrices made of styrene-divinylbenzene, polymethacrylate, polyhydroxymethacrylate, and polyvinyl alcohol. Selectivity arises either from the intrinsic polymer surface or from additional sulfo, carboxyl, or ammonium groups. As a result, the product family ranges from polymeric reverse-phase columns to HILIC-like distribution, as well as mixed-mode, ligand-exchange, and ion-exclusion mechanisms. The silica-free packing materials are particularly suitable for extreme pH values and highly aqueous mobile phases.
