Asahipak GS-710 20G 500x20mm Multisolvent GPC Preparative Column

The Asahipak GS-710 SEC column 500x20mm, 13µm, is packed with a hydrophilic polyvinyl alcohol gel with a nominal pore size of 10,000 Å. Asahipak GS-710 typically covers a molecular weight range of approximately 100,000 to 10,000,000 Da for pullulan and 20,000 to 10,000,000 Da for PEG/PEO and transfers the wide-pore GF-710-HQ separation characteristics to larger, in particular preparative, column formats. The 20F and 20G versions are intended for water and methanol. For other organic eluents the multisolvent version GSM-700 is used. 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.
