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: 1.9 µm, spherical
• Pore Size: 140 Å, End-Cap: no
• pH Range: 2.5 to 8
• Temperature Limit: 80 °C
• USP Phase Code: L68
• Phase Category: polar-embedded alkyl
• Ligand Type: 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.
