Columns for UHPLC
Chromatographic Properties
The Restek® IBD 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 reten-
tive 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.
