Asahipak ES-502N 20C 100x20mm Silica based Preparative Column

The Asahipak ES-502N 7C HPLC column 100x20mm, 13µm, contains diethylaminoethyl groups as a weak anion exchanger on a macroporous polyvinyl alcohol gel. Negatively charged proteins and other biomolecules are bound via electrostatic interactions and eluted using salt or pH gradients. The hydrophilic PVA backbone minimises hydrophobic secondary interactions. Typical application areas of Asahipak ES-502N 7C are proteins, enzymes, nucleic acids and other anionic biomolecules.

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.
