Asahipak C8P-50 10E 250x10mm Polymer based Preparative Column

The Asahipak C8P-50 HPLC column 250x10mm, 5µm, has an octyl modification (other designations: RP-8, C8) on porous polyvinyl alcohol with a nominal pore size of 250 Å. Asahipak C8P-50 produces lower hydrophobic retention than a C18 phase, yet stronger than C4P-50, thereby extending the selectivity gradation within polymer-based reversed phases. The phase is used over a wide pH range for peptides, proteins and moderately hydrophobic organic compounds.

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.
