HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 3 µm, 300 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.

Mac-Mod Fortis SpeedCore AQUA, 80 A, 5 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.
Microsolv Technology Corporation Guard Column Cartridges, RP C18, 10um, 100A. 4.0mm ID x 10mm Length. 5/PK.
These Guard Column Cartridges are packed with 10µm, Cogent RP C18™ Stationary Phase. They are double end capped ( fully ), with traditional bonding of an 18 carbon silane to the highest purity silica available. Designed to protect your 3.0, 4.0 or 4.6mm ID, RP C18, Analytical Columns from particulate and contaminants that will adsorb to it. They are packed in Stainless Steel Tubes and have Stainless Steel Frits that are pressed into PEEK Frit Caps. These Guard Column Cartridges must be used with a Guard Column Holder.
Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, Zenix-C SEC-300, 3 µm, 4.6 x 50 mm, Light Scattering SEC
Zenix™-C SEC phase, developed based on innovative surface coating technology, comprises of uniform, hydrophilic, and neutral nanometer thick film chemically bonded to high purity and mechanically stabilized silica. Zenix™-C, uses lay-down monolayer on porous silica as oppose to Zenix of stand-up monolayer, offers ideal phase chemistry for hydrophobic samples like insulin, membrane protein monoclonal antibodies derivatized with polymer branches (polypeptide or PEG) separation. The 3µm based packing material allows for high resolution and performance separation.

Sepax Technologies Inc Sepax HPLC Column HP-Cyano, 3 µm, 120 Å, 4 x 10 mm
Synthesized with monomeric and fully endcapped chemistry, HP-Cyano phase is bonded with propylcyano functional group that allows special interaction with polar compounds. The monomeric bonding chemistry enables high efficiency and high resolution separation of peptide, proteins, acidic, neutral and basic organic compound, and pharmaceuticals.
Sepax Technologies Inc Sepax HPLC Column PolyRP-100, Guard cartridge with holder, 10 µm, 2 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 GP-C4, 5 µm, 120 Å, 4 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 BR-C18, 5 µm, 120 Å, 4 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, BR-C18 bonded phases have been innovatively and specially designed to ensure maximum surface coverage and full end-capping, which leads to carbon content as high as 19.0%. The bonding chemistry is completely controlled that results in very reliable column-to-column reproducibility. The maximum surface coverage allows BR-C18 to have exceptional stability, resulting in high pH stability in the range of 1.5 to 10.5.
