Alltech® column families include reversed-phase, normal-phase, HILIC, ion-exchange, ion-exclusion and size-exclusion stationary phases for small- and large-molecule separations.

Alltima™ HP phases are made from high purity silica to eliminate peak tailing. Proprietary bonding eliminates the problem of column bleed for MS and ELSD detection.

Prevail™ phases are designed for wettability with aqueous and organic mobile phases, and are especially useful for broad gradients. Retain highly polar analytes with aqueous mobile phases as well as hydrophobic analytes in organic mobile phases.

Platinum™ phases have a controlled polar silica surface which provides enhanced polar selectivity (EPS) in addition to reversed-phase retention.
