Sepax Technologies Inc Sepax HPLC Column Antibodix WCX, NP5, Guard cartridge with holder, 2 x 10 mm
Antibodix columns are specially designed for high resolution, high efficiency and high recovery separations of antibodies. The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead. The non-porous resin has particle size of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. On the top of the hydrophilic layer, weak cation-exchange functional groups are attached via a proprietary chemistry, resulting in high capacity ion-exchange layer.
Sepax Technologies Inc Sepax HPLC Column Bio-C8, Guard cartridge with holder, 3 µm, 300 Å, 4 x 10 mm
Bio-C8 phase is made of monomeric and fully endcapped chemistry. The uniform stationary phase allows the separation to achieve high selectivity and high efficiency. Bio-C8 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins.
Sepax Technologies Inc Sepax HPLC Column GP-C18, Guard cartridge with holder, 3 µm, 120 Å, 2 x 10 mm
GP-C18 uses full coverage bonded silica packing, which provides exceptionally high stability. The unique mono-functional bonding chemistry of GP-C18 avoids the formation of multiple C18 layers. Such uniform stationary phase allows the separation to achieve high selectivity and high efficiency.
Sepax Technologies Inc Sepax HPLC Column Proteomix WAX, NP1.7, Guard cartridge with holder, 2 x 10 mm
Sepax HPLC Column Proteomix WAX, NP1.7, Guard cartridge with holder, 2 x 10 mm
Sepax Technologies Inc Sepax HPLC Column Proteomix SCX, NP5, Guard cartridge (No Holder), 2 x 10 mm
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 with particle size selections of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. 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.
Sepax Technologies Inc Sepax HPLC Column Polar-Imidazole, 5 µm, 120 Å, 4 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, Polar-Imidazole phase is bonded with imidazole functional groups. With a polar and N-containing ring structure, Polar-Pyridine phase is a weak base and adequate for many applications, such as pharmaceuticals, peptides, sugars, and nucleotides.

Sepax Technologies Inc Sepax HPLC Column PolyRP-100, 5 µm, 4 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Sepax Technologies Inc Sepax HPLC Column Bio-C4, 5 µm, 300 Å, 4 x 10 mm
Monomeric and fully endcapped Bio-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. Bio-C4 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of intact proteins, and natural and synthetic peptides.
Sepax Technologies Inc Sepax HPLC Column PolyRP-1000, 10 µm, 4 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 3 µm, 200 Å, 2 x 10 mm
Wide range of pore sizes and high compatibility with 100% aqueous phases make Bio-C18 columns ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. The specially designed surface bonding chemistry and the pore sizes allow for extended retention and selectivity for polar and hydrophilic compounds, such as peptides and amino acids. C18 monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
