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. An intrinsically base-deactivated (IBD) phase, containing a polar group within, or intrinsic to, the hydrocarbon bonded phase. Unique selectivity and a high level of base deactivation, while reducing or eliminating the need for mobile phase additives.
