HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 5 µm, 200 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 Proteomix SAX, 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.
Optimize Technologies EXP Trap Cartridge, 1.5mm x 5mm, 3.0µm EXP, 3.0µm EXP, C18, 3pk
The Hand-Tight EXP™ Trap Column is rated to 20,000+ psi. This unique design connects directly to any injection valve (with 10-32 threads) or in-line with 1/16” tubing for unparalleled convenience and efficiency. The EXP™ System enables chemists to quickly remove detergents or salts which can affect the ionization process in MS work. This trapping technique can concentrate the sample directly on-line, allowing for increased recovery of precious sample material compared to off-line techniques. Free-Turn™ architecture allows users to change cartridges by hand without breaking fluid connections on the holder inlet/outlet. The EXP™ Trap Column family now offers packed beds available in 2, 5, 10, 15, 20 and 30mm lengths with diameters ranging from 1-4.6mm and bed volumes from 1.6-600µL. Please contact your representative directly if you're interested in a length other than 5mm.
Mac-Mod Avantor Prevail C18-Select, 110 Å, 5 µm, 3.0 x 7.5 mm Guard Cartridges (3/pk)
Avantor Prevail HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. Avantor Prevail HPLC columns are silica based except for Prevail Carbohydrate ES. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes. Avantor Prevail HPLC columns are stable from highly organic to highly aqueous. Avantor Prevail HPLC columns are specialty phases for specific applications. Avantor Prevail HPLC columns provide excellent sensitivity with microbore and ELSD applications.
Mac-Mod Avantor ACE C4, 100 Å, 5 µm, 3.0/4.6 x 10 mm Guard Cartridges (5/pk)
Avantor ACE Excel UHPLC and HPLC columns are manufactured with 100 Å Ultra-Inert Base Deactivated Silica specifically designed for your HPLC method development needs - Note SuperC18 is 95 Å Avantor ACE HPLC columns are available in a wide range of bonded phases (i.e. C18, C18-AR, C18-PFP, C18-Amide, CN-ES, SuperC18, NH2, C8, C4, Phenyl, AQ, CN and Sil). Avantor ACE Excel UHPLC and HPLC columns are avaialble in 1.7, 2, 3, and 5 µm particle sizes in all analytical column sizes. All Avantor ACE Excel columns are known for their excellent peak shape and batch to batch reproducibility. Columns are packed in 1000 bar UHPLC hardware. Note: Avantor ACE Excel UHPLC guard columns are available for all 1.7 and 2 µm particle sizes across all 2.1 mm - 4.6 mm column ID - Note: H0011 connects directly to the analytical column - Guard column cartridges are available in 3-packs. For 3 and 5 µm Excel columns use same guard systems used for Avantor ACE HPLC analytical columns.
