Sepax Proteomix Ion-exchange UHPLC Columns
Description
Proteomix ion-exchange phases have been innovatively developed for achieving high ion-exchange
capacity, a breakthrough technology for non-porous resins. Proteomix packing support is composed
of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead.
The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer, with
thickness in the range of nanometers. The hydrophobic PS/DVB resin surface is totally covered by a
hydrophilic coating that eliminates non-specific bindings with biological analytes, leading to high
efficiency and high recovery separations for biological molecules. On the top of the hydrophilic layer,
ion-exchange functional groups are attached via a proprietary chemistry, resulting in a high capacity
ion-exchange layer.
