Sepax Technologies Inc Sepax HPLC Column Proteomix SAX, NP5, Guard cartridge (No Holder), 2 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.
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.
Waters Corp SunFire C18 Prep Guard Cartridge, 100Å, 10 µm, 30 mm X 10 mm, 1/pk;
SunFire C18 Prep Guard Cartridge, 100Å, 10 µm, 30 mm X 10 mm, 1/pk;
Waters Corp XBridge BEH Amide Prep Guard Cartridge, 130Å, 5 µm, 10 mm X 10 mm, 1/pk
XBridge BEH Amide columns retain extremely polar compounds, including carbohydrates and sugars. XBridge Amide columns offer you a chemically stable, trifunctionally bonded amide phase that is stable from pH 2 to 11 to enable the separation of polar analytes spanning a wide range of polarity, structural moiety and pKa.
Mac-Mod Avantor ACE UltraCore SuperPhenylHexyl, 95 Å, 2.5 µm, 2.1/3.0 x 5 mm UHPLC Guard Cartridges (3/pk)
Avantor ACE UltraCore solid-core (core-shell) particle columns are ideal for MS work offering improved signal intensity and maximum response. These columns combine high efficiency separations with low back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability. Solid Core particle technology provides higher efficiencies per unit back pressure as compared to sub-2-micron UHPLC columns. Columns combine the proven advantages of UHPLC and HPLC columns with Solid Core Particle Technology. Solid-core columns can be used on both UHPLC and HPLC systems. Excellent peak shape and phases stability with extended pH. Highly inert, ultra-low bleed, designed for use with LC/MS compatible buffers. 2.5 and 5 µm particle sizes available.

Optimize Technologies EXP Trap Cartridge, 2.1mm x 5mm, 3.0µm EXP, 3.0µm EXP, C8, 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.
