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

With the Asahipak ES-502C HPLC column 100x20mm, 13µm, carboxymethyl groups are used as a weak cation exchanger on a macroporous polyvinyl alcohol gel. Positively charged biomolecules are retained depending on pH value and ionic strength. The large-pore, hydrophilic matrix supports good accessibility for macromolecules. Typical applications of Asahipak ES-502C 7C are basic proteins, peptides, enzymes and other cationic target molecules.

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.
