Product Description
The OHpak SB-802 HQ SEC column 300x8.0mm, 8µm, contains a hydrophilic polyhydroxymethacrylate gel with a nominal pore size of 100 Å. In aqueous size-exclusion chromatography OHpak SB-802 HQ covers a typical molecular weight range of approx. 200 to 1.000 Da and is particularly suitable for oligomers, polyols and very low-molecular-weight water-soluble polymers. The small pore focuses resolution in the oligomer range. The stated molecular weight ranges are nominal, calibration-dependent guidance values.
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.
