Asahipak ODP-50 4D, 4.6 x 150 mm, HPLC column

The Asahipak ODP-50 HPLC column 150x4.6mm, 5µm, has an octadecyl modification (other designations: ODS, RP-18, C18) on a porous polyvinyl alcohol substrate. The polymer-based C18 phase can be used in reversed-phase chromatography across a wide pH range and can also be operated with highly aqueous eluents.Asahipak ODP-50 combines hydrophobic retention with low unwanted adsorption and is suitable, among other things, for basic active substances, amino acids, peptides and proteins.

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.
