The Asahipak ODP-40 HPLC column 150x3.0mm, 4µm, features an octadecyl modification (other designations: ODS, RP-18, C18) on porous polyvinyl alcohol with a nominal pore size of 250 Å. With the 4µm particle format, Asahipak ODP-40 achieves higher chromatographic efficiency compared with ODP-50 while maintaining comparable polymer-based reversed-phase selectivity. The phase is usable over a wide pH range and is employed for pharmaceuticals, basic compounds, peptides and other hydrophobic analytes.
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.
Asahipak is a registered trademark of the manufacturer, Resonac Corporation, Tokyo, Japan.
