Asahipak NH2P-40 3E, 3.0 x 250 mm, HPLC column

The Asahipak NH2P-40 HPLC column 250x3.0mm, 4µm, contains an amino modification on a polyvinyl alcohol backbone. With 4 µm particles, Asahipak NH2P-40 is designed for higher chromatographic efficiency in hydrophilic interaction chromatography.The phase separates mono-, di- and oligosaccharides, sugar alcohols and other highly polar compounds, delivering particularly good recovery for reducing sugars.

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.
