Ultra IBD Columns (USP L68), Particle Size 5 μm, Length 250 mm, ID 2.1 mm, Restek (CAT#: STEM-C-0970-LC)

The Ultra IBD Columns (USP L68) manufactured by Restek is a polar-embedded column that acts as a strong hydrogen bonder and may be the most versatile column available today. With a unique polar group, this column is very retentive and selective for acids. It also offers symmetrical peak shape for strong bases. The column 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.
