RSpak DE-2013 300x20mm Polymer based Preparative Column

The RSpak DE-2013 preparative HPLC column 300x20mm, 12µm, is packed with polymethacrylate without additional bonded ligands. RSpak DE-2013 transfers the selectivity of the analytical DE-413 and DE-613 phases to higher sample loadings and can also be operated with fully aqueous mobile phases. Typical applications are the preparative fractionation of polar pharmaceuticals, vitamins, preservatives and organic acids.

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.
