Descripción
Resonac Shodex OHpak LB-805 7000Å 13µm, 8.0 x 300mm Analytical Column, ea.
Polymer-based packed columns for aqueous SEC (GFC) analysis.
Low column bleeding allows its use with light scattering detectors.
The eluent can be replaced with DMF enabling the analysis of polar polymers.
LB-802.5 (exclusion limit: about 10,000) newly added to the series.
Fulfills USP L25 – Packing having the capacity to separate compounds with a molecular weight range from 100-5000 (as determined by polyethylene oxide), applied to neutral, anionic, and cationic water-soluble polymers. A polymethacrylate resin base, cross-linked with polyhydroxylated ether (surface contained some residual carboxyl functional groups) was found suitable.
Fulfills USP L89 – Packing having the capacity to separate compounds with a molecular weight range from 100 to 3000 (as determined by polyethylene oxide), applied to neutral and anionic water-soluble polymers. A polymethacrylate resin base, cross-linked with polyhydroxylate ether (surface contains some residual cationic functional groups).
OHpak LB-805 Possible Applications:
• Nucleic acids – DNA / RNA – SEC
• Polysaccharides – SEC
