RSpak KC-811, 8.0 x 300 mm, HPLC column

The RSpak KC-811 HPLC column 300x8.0mm, 6µm, is packed with a sulfonated styrene-divinylbenzene resin in hydrogen form. RSpak KC-811 separates by ion exclusion and additional hydrophobic interactions and is particularly suitable for organic acids in fermentation, food and process samples. In addition, the column can be used for cyanide and chlorocyanide in aqueous matrices.

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.
