Description
The Restek Ultra IBD column is part of Restek’s Ultra line, offering a broad selection of stationary phases on a single silica support. Made from high-purity, type-B silica that minimizes activity and enables high-density bonding, these columns deliver selective and reliable performance in HPLC applications.
The IBD is a polar-embedded column that functions as a strong hydrogen bonder, providing versatility across a wide range of analytes. Its unique polar group ensures high retention and selectivity for acidic compounds, while maintaining symmetrical peak shapes for strong bases. This column is compatible with 100% aqueous mobile phases and can be used under both reversed-phase and HILIC conditions to retain very polar or ionic compounds in highly organic mobile phases.
