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 GP-C18, 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 GP-C4, 5 µm, 120 Å, 2 x 10 mm
Monomeric and fully endcapped GP-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. GP-C4 columns have unique selectivity and peak symmetry with moderate retention for separations of acidic, neutral and basic organic compounds, such as pharmaceuticals, peptides, and organic acids.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 5 µm, 300 Å, 4 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.
Sepax Technologies Inc Sepax HPLC Column HP-SCX, 5 µm, 120 Å, 2 x 10 mm
HP-SCX is a silica based mixed-mode strong cation exchange phase. The phase has a mixed chemical structure of sulfonic acid and phenyl group. The mixed mode of strong cation-exchange and hydrophobicity offers unique selectivity and high resolution separation for cationic/basic and nitrogen containing compounds as well as desirable retention for a variety of weak cationic and neutral organic compounds. The uniform polymeric bonding of HP-SCX enhances its stability under various separation conditions.HP-SCX has expanded its applications from the traditional SCX separation of cationic and nitrogen containing compounds to weak cationic and neutral organic molecules. Examples include separation of analytes of amines and polyamines, such as alkaloids, peptides, codeine, and cough and cold ingredients.

Sepax Technologies Inc Sepax HPLC Column Proteomix HIC Phenyl-NP5, Guard cartridge with holder, 4 x 10 mm
Proteomix HIC columns are specially designed for high resolution and high efficiency separations of proteins, monoclonal antibodies (mAbs), antibody drug conjugates (ADCs), oligonucleotides and peptides via a hydrophobic interaction chromatography (HIC) mechanism. Utilizing proprietary surface technologies, Proteomix HIC-NP resin is made of non-porous polystyrenedivinylbenzene (PS/DVB) beads with narrow-dispersed particle size distribution. As shown in figure below, the PS/DVB bead is modified with alkyl groups or aryl groups that provide hydrophobic interaction with analytes. Proteomix HIC-NP resin is highly rigid and mechanically stable. In comparison to silica-based HIC phase media, Proteomix HIC-NP phases have advantages for biomolecule separations with a wide pH range (2-12) and high chemical stability.
