Asahipak NH2P-50 10E, 10.0 x 250 mm, preparative HPLC column

The Asahipak NH2P-50 HPLC column 250x10mm, 5µm, based on an amino-functionalised polyvinyl alcohol matrix. Asahipak NH2P-50 is used in HILIC and is less susceptible to the hydrolytic ageing processes typical for amino-modified silica phases. In addition to sugar analysis, the robust phase is suitable for ELSD, CAD and LC-MS methods; if performance declines, the polymer material can be regenerated under suitable alkaline conditions.

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.
