Sepax Technologies Inc Sepax HPLC Column HP-SCX, 3 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 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.
Waters Corp BioSuite Diol (OH) Guard Column, 5 µm, 6 mm X 40 mm, 1/pk
BioSuite SEC Columns are available in 4.6 mm, 7.5 mm, and 7.8 mm i.d. analytical and 21.5 mm i.d. preparative and guard columns.
Optimize Technologies EXP2 Replacement Stems, 0.33µL, 3.0µm EXP, C18, 3pk
Specialized features, patented technology, precision engineering and state-of-the-art manufacturing make the new EXP2 Stem Trap an unbeatable choice for ultra high-pressure trapping applications. Its slim architecture allows it to easily fit into crowded instrument compartments or to connect directly to tightly-spaced injection ports. When tightened by hand, the EXP2 Stem Trap seals to 8,700+ psi. Additionally, the product can be wrench tightened to 20,000+ psi (1,400+ bar). The unique packed floating stem installs directly into any 10-32 port and automatically adjusts to provide a perfect ZDV connection. The new EXP2 design incorporates an integral ferrule into the front-end of the holder so there is no separate ferrule to lose! The replacement stems are also low volume/ low-dispersion, intended for many repeat uses and is available with various bed volume and custom packing options. This product is recommended for nano flow applications. For use with EXP™2 Stem Holder Only

Sepax Technologies Inc Sepax HPLC Column Proteomix WAX, NP5, Guard cartridge with holder, 4 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.
