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 mono-functional 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. Those high rigid particles have both non-porous and porous structures with the particle selection of 1 and 1.7 µm. The phase structure is phenyl functional group that enables 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 the thickness in the range of nanometers, which shields the hydrophobic PS/DVB core and eliminates their 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 high capacity ion-exchange layer.
