Product Description
The RSpak KC Guard Columns 50x8.0mm, 13µm, are used to protect RSpak KC HPLC columns used. The phase-identically packed guard columns are complete pre-columns and are operated without a separate cartridge holder.
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.
