The OHpak LB-806M low-bleed SEC column 300x8.0mm, 13µm, contains a controlled low-bleed polyhydroxy methacrylate gel with a nominal pore size of 15,000 Å as a mixed-pore gel. OHpak LB-806M is tuned to a typical molecular weight range of approximately 500 to 20,000,000 Da, enabling broadly distributed polymers and polysaccharides to be differentiated. The reduced release of soluble polymer components improves coupling with light-scattering, viscosity and other sensitive detectors. 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.
