Asahipak GF-210 4D 4,6x150mm

The Asahipak GF-210 SEC column 150x4.6mm, 5µm, contains a hydrophilic polyvinyl alcohol gel with a nominal pore size of 180 Å. Asahipak GF-210 typically covers a molecular weight range of approximately 300 to 4,000 Da for pullulan and 100 to 2,000 Da for PEG/PEO; the nominal exclusion limit is approximately 9,000 Da. The compact column format enables SEC of oligosaccharides and low-molecular-weight water-soluble polymers with aqueous or polar-organic eluents. The stated molecular weight ranges are nominal, calibration-dependent orientation values.

Features and Benefits

• Hydrophilic polyvinyl alcohol matrix
• Multiple separation mechanisms available
• Broad solvent and pH compatibility
• Low nonspecific adsorption
• Analytical and preparative formats

Additional Information

The Asahipak product family is primarily based on porous polyvinyl alcohol particles. The hydrophilic polymer backbone is chemically stable and, compared to silica, produces only minimal undesirable interactions with basic compounds or biomolecules. Reverse-phase, HILIC, ion exchange, and size exclusion chromatography are supported through C18, C4, amino, and ion-exchange modifications, as well as defined pore sizes. Same-phase guard columns protect the packing bed from particles and highly retained matrix components.
