Asahipak GS-520 HQ 300x7.5mm Gel Filtration (GFC) Multimode

The Asahipak GS-520 HQ HPLC column 300x7.5mm, 7µm, contains a porous polyvinyl alcohol gel with a nominal pore size of 2,000 Å. In SEC or multimode chromatography Asahipak GS-520 HQ typically covers a molecular weight range of approx. 5,000 to 200,000 Da for pullulan with an exclusion limit of approx. 300,000 Da. In addition to size exclusion, hydrophobic and ionic interactions can be influenced via the eluent composition. Typical applications are proteins, polysaccharides and larger water-soluble polymers. The stated molecular weight ranges are nominal, calibration-dependent orientational 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.
