Ultisil XB Normal Phase columns are based on ultra-pure ( purity > 99.999% ) type B spherical and totally porous silica. Bare silica, Diol, and NH2 (Amine) are used for normal phase separations; with Diol and NH2 often able to deliver more stable results. Diol and NH2 have the added benefit of reduced sensitivity to the presence of water. Diol and NH2 can also be used in reversed-phase.

Ultisil XB-NH2 column is based on propyl-amino silane, mostly used in normal phase, but can also be used in reversed phase. When used in normal phase, the retention mode is weak anion-exchange, while in reversed-phase, it can be used for separation of polar compounds. It is suitable for applications in aggressive normal phase mode with aqueous eluent.
