RSpak KC-2011 300x20mm Sugar Preparative Column

The RSpak KC-2011 preparative HPLC column300x20mm, 20µm, is packed with a styrene-divinylbenzene resin with sulfo groups in hydrogen form. RSpak KC-2011 transfers the ion-exclusion mechanism and the additional reversed-phase selectivity of KC-811 to higher sample loadings. The column is suitable for preparative fractionation of organic acids from fermentation, food and process samples.

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.
