RSpak DE-613, 6.0 x 150 mm, HPLC column

The RSpak DE-613 HPLC column 150x6.0mm, 6µm, is packed with a fine-porous polymethacrylate gel without additional ligands. The intrinsic surface polarity produces a C18-like yet distinct reversed-phase selectivity and permits operation with fully aqueous eluents. RSpak DE-613 can be used across a wide pH range and is suitable for polar actives, organic acids and basic compounds.

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.
