Asahipak NH2P-LF 75x8mm Polymer based Reversed & HILIC Column

The Asahipak NH2P-LF Line Filter 75x8.0mm, 5µm, is packed with NH2P material on a polyvinyl alcohol base and is installed in the flow path between pump and injector. Asahipak NH2P-LF retains contaminants from the eluent, thereby improving the reproducibility of NH2P analyses and can be regenerated under appropriate conditions. As the line filter is positioned before the injector, it does not protect against sample matrix components and does not replace either a guard column or sample preparation.

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.
