The OHpak SB-2006 preparative SEC column 300x20mm, 20µm, is based on a hydrophilic polyhydroxy methacrylate gel with a nominal pore size of 15,000 Å. For very high-molecular-weight polymers, OHpak SB-2006 provides a nominal molecular weight range of approximately 100,000 to 20,000,000 Da. The larger column format enables higher sample loads and fractionation in scale-up. The stated molecular weight ranges are nominal, calibration-dependent guideline values.
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.
OHpak is a registered trademark of the manufacturer Resonac Corporation, Tokyo, Japan.
