RSpak DE-213, 2.0 x 150 mm, HPLC column

The RSpak DE-213 HPLC column 150x2.0mm, 4µm, is a narrower polymethacrylate reversed-phase column for semi-microchromatographic applications. RSpak DE-213 combines the wide pH operating range of the DE series with reduced solvent consumption and increased MS sensitivity. The phase is intended for small polar organic compounds and LC-MS methods at low flow rates.

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.
