- An intrinsically base-deactivated (IBD)
phase, containing a polar group within, or intrinsic to, the hydrocarbon bonded phase.
- nique selectivity and a high level of base deactivation, while reducing or eliminating the need for mobile phase additives.
- particle size: 3 or 5µm, spherical
- temperature limit: 80°C
The polar group in Ultra IBD columns assists in deactivating surface silanols and participates in providing unique separation selectivities for acids, bases,
zwitterions, and other polar compounds.
