Andwin Scientific CHROMOLITH SPEEDROD RP-18
The Merck Chromolith HPLC columns is ideal for use in combinatorial chemistry. The columns offer a quick and high-quality performance of separating acidic, basic, nonpolar, and metal chelating compounds. This product has a dimension of 4.6 x 50 mm, a macropore size of 2 mm, a micropore size of 13 nm, a pore volume of 1 mL/g, and a surface area of 300 square meters/g.
Waters Corp XSelect CSH C18 Prep Guard Cartridge, 130Å, 5 µm, 10 mm X 10 mm, 1/pk
XSelect CSH C18 columns can be used as general purpose columns that provide alternative selectivity compared to other C18 sorbents. Charged Surface Hybrid (CSH) technology helps you overcome column related problems such as peak shape asymmetry and poor loading for basic compounds, column bleed, and slow mobile-phase re-equilibration.

Sepax Technologies Inc Sepax HPLC Column HP-Amino, Guard cartridge with holder, 3 µm, 120 Å, 2 x 10 mm
Synthesized with polymeric chemistry, HP-Amino phase is bonded with aminopropyl functional group. HP-Amino phase is compatible with versatile mobile phases from non-aqueous solvents, such as hexane/ethyl acetate and chloroform/methanol, to aqueous solutions. It is recommended for separations of sugars, nucleotides, basic organic compounds, as well as the pharmaceuticals.
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.
Waters Corp µBondapak C18 Guard-Pak Insert, 125Å, 10 µm, 10/pk
µBondapak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 10 µm particle technology. As a starting point for preparative chromatography, no other column can provide the balance between resolution, throughput and cost.
Sepax Technologies Inc Sepax HPLC Column Proteomix HIC Propyl-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.
Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, Zenix SEC-300, 3 µm, 7.8 x 50 mm, Light Scattering SEC
Made of 3 µm silica particles, Zenix SEC packing is a breakthrough technology for size exclusion chromatography. Combination of 3 µm silica particle size and proprietary surface technology enables highest separation efficiency and resolution for biological molecules and water soluble polymers. Available pore sizes of Zenix packings are 80, 100, 150 and 300 Å
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.
