Product Description
The OHpakLB guard column 50x6.0mm, 13µm, protect OHpakLB SEC columns. The guard columns are packed with the same phase and are used as complete guard columns without a separate cartridge holder.
Features and Benefits
- Hydrophilic methacrylate-based SEC gels
- Very wide molecular weight range
- Low-bleed phases for light-scattering detection
- Aqueous and selected polar organic eluents
- Analytical and preparative formats
Additional Notes
OHpak is based on porous polyhydroxymethacrylate gels with graded or mixed pore distributions. The hydrophilic polymer surface is optimized for aqueous SEC and can also be adapted for use with DMF in many SB and LB phases; exceptions and adaptation procedures depend on the specific product. The LB series features controlled, low column bleeding for MALS and viscosity detectors, while the SB-2000 series allows for higher loadings on a preparative scale.
