These biphenyl columns offer a greater degree of dispersion than conventional phenyls and a greater degree of polarizability than phenyl hexyls, creating higher selectivity and a greater range of usability. Because of these heightened interactions, this column shows substantial increases in retention—especially for dipolar, unsaturated, or conjugated solutes—and enhanced orthogonal selectivity when using methanol mobile phases.

Supplier: Thermo Fisher Scientific

These reversed phase columns were developed in conjunction with the Vanquish™ UHPLC system to take advantage of the system's extended pressure capabilities and robustness. The result is a new level of separation, speed and throughput that solve analytical challenges of analysing complex matrices using liquid chromatography and LC-MS.

Efficient separation of difficult mixtures containing closely related halogenated and polar compounds. The introduction of a fluorine group into the stationary phase causes significant changes in solute-stationary phase interaction and increases the selectivity and extra retention.

Supplier: Restek

Highly base-deactivated spherical silica manufactured by Restek. Monomeric C8 bonding. Similar to Pinnacle® DB C18, but the shorter alkyl chain provides less hydrophobic retention. Less retention can be useful for shortening analysis time, if resolution is adequate. Replaces Hypersil® BDS C8 and Pinnacle® C8 Amine.
