Asahipak GSM-700 20F 300x20mm Gel Filtration (GFC) Multimode Preparative Column

The Asahipak GSM-700 multisolvent SEC column 300x20mm, 13µm, is packed with a hydrophilic polyvinyl alcohol mixed gel. Asahipak GSM-700 typically covers an exceptionally broad molecular weight range of approximately 300 to 10,000,000 Da for pullulan and 200 to 10,000,000 Da for PEG/PEO. The mixed-pore bed enables investigation of broadly distributed polymers from oligomers to high-molecular-weight species. As a multisolvent version the phase supports, in addition to water and methanol, other organic eluents and has been used in analytical as well as preparative formats. 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.
