Sepax UHPLC Columns

Silica Based
Sepax UHPLC silica packings use high purity (<10 ppm metals) spherical silica with the particle selection of 1.8 and 2.2 µm and the pore size of 120 Å. Their bonded phases include C18, C8, C4, Phenyl, Amino, Cyano, strong anion, strong cation, and HILIC. Their unique bonding chemistry allows high efficiency, high selectivity and high speed separation. All sub-2 micron particles and bonded phases have excellent resistance to high pressure (>10,000 psi).

PolyRP Phases
PolyRP phases are made of 80% cross-linking PS/DVB spherical particles. These highly rigid particles have both non-porous and porous structures with the particle size of 1.7 µm. The phase structure is phenyl functional groups that enable hydrophobic interaction. Compared with silica based reversed phases, PolyRP phases have advantages over applications at extreme pH (1-14) with special selectivity and slightly lower separation efficiency.

Proteomix Ion-exchange Phases
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.
