HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column GP-C18, 5 µm, 120 Å, 4 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.
Waters Corporation Radial-Pak Guard, C4, 15 μm, 300 Å, 25 mm x 10 mm
These packings separate peptides, proteins, and natural products. They utilize stable, bonded, endcapped 5μm or 15μm spherical silica. Available with C4 or C18 bonded phases and 100Å or 300Å pore sizes, they provide consistent scale-up for purification. A 5μm particle option aids purity checks.

Advanced Materials Technology HALO 90 Å PCS Phenyl-Hexyl, 2.7um, 1.5 mm x 50 mm
Built upon proven Fused-Core technology for speed and efficiency, the HALO PCS column products are positively charged surface chemistries designed to deliver improved peak shapes for basic compounds observed with standard Phenyl-Hexyl chemistry. Ideal for use with low ionic strength mobile phases, HALO PCS maintains peak symmetry at higher loading capacities and provides alternate selectivities from Phenyl-Hexyl bonded phases. The columns are optimized to deliver performance for reproducible, high efficiency LC and LCMS separations.
Mac-Mod Fortis SpeedCore AQUA, 80 A, 2.6 um, 2.1 x 50 mm Core Shell Column
Fortis SpeedCore Core-Shell columns are the very latest in Core-Shell technology. Incorporating optimized bonding density and unique stringent packing processes, the new 80 A Core-Shell columns provide the chromatographer with the ability to speed up analysis and increase resolution over traditional fully porous 3 and 5 micron materials. Fortis SpeedCore is available in a wide range of bonded phase chemistries including C18, C18 pH+, C18-PFP, C8, Diphenyl, RP18-Amide, AQUA, and PFP bonded phases and 2.6 and 5 um particle sizes. Fortis SpeedCore columns are available in analytical formats.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 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.
