RSpak NN-414 150x4.6mm Polymer based Normal & Reversed Phase Column

The RSpak NN-414 HPLC column 150x4.6mm, 10µm, uses polyhydroxy methacrylate with 200Å pores and bonded sulfonic groups. By combining hydrophilic, reversed-phase and cation-exchange interactions RSpak NN-414 differentiates neutral and charged components with reduced solvent consumption. The phase is suitable for organic acids, amino compounds, basic active pharmaceutical ingredients and polar mixtures.

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.
