RSpak DM-2014 300x20mm Polymer based Preparative Column

The RSpak DM-2014 preparative HPLC column 300x20mm, 12µm, contains polyhydroxymethacrylate without hydrophobic ligands. RSpak DM-2014 transfers the hydrophilic selectivity of DM-614 to a higher-load format and enables the preparative separation of small water-soluble compounds. The phase is used particularly for amino acids, water-soluble vitamins, organic acids and other polar 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.
