The Restek IBD is a polar-embedded column that acts as a strong hydrogen bonder and may be the most versatile column available today.
- Particle size: 3 or 5 µm, spherical
- Pore size: 100 Å
- Carbon load: 12%
- End-cap: no
- pH range and temperature limit: 2.5 to 8 and 80 °C
- USP phase code: L68
- Phase category and ligand type: polar-embedded alkyl and proprietary polar functional embedded alkyl
With a unique polar group, this column is very retentive and selective for acids. It also provides symmetrical peak shape for strong bases. Restek’s IBD is compatible with 100% aqueous mobile phases and can be used under reversed-phase or HILIC conditions to retain very polar, ionic compounds in highly organic mobile phases.
