• 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.
