Sepax Proteomix Ion-exchange UHPLC Columns
DescriptionApplicationOrder InfoDownloads
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.
