HPLC Guard Columns and Cartridges
Mac-Mod Princeton Pyridine Amide 60 Å, 5 µm, 4 x 10 mm Guard Cartridges (5/pk)
Princeton Chromatography Achiral SFC columns are designed and manufactured in the US, well known for innovating novel and robust workhorse phase chemistries, for the analysis of achiral SFC applications. Princeton designs myriad phase chemistries to improve the selectivity and efficiency of SFC analysis. Known for originally innovating the 2-EP phase chemistry, explore what Princeton has to offer. Columns are available from analytical to preparative sizes and are available in a wide range of pore sizes, particle sizes, column ID's and lengths. If you do not see something that you want, please just ask!

Sepax Technologies Inc Sepax HPLC Column Proteomix SCX, NP3, 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.
Mac-Mod Vydac 218TP C18, 300 A, 12 um, 10.0 x 10 mm Prep Cartridge
Vydac TP was the first range of wide pore media phases developed and became the industry standard for peptide and protein separations. The 300 TP silica gives polypeptide molecules complete access to the interior of the silica pores. Vydac TP is known for long column lifetime and negligible phase leaching. Vydac TP provides reliable protein purifications, scalable from analytical to preparative scale. Vydac 218TP and 238TP are used for small polypeptides of 4-5kDa, enzymatic digest fragments, natural and synthetic peptides and multi-ring compounds. Vydac 208TP is recommended for polypeptides of molecular weight 10-20kDa. Vydac 214TP is recommended for the analysis of glycoproteins, hemoglobin variants, histones, insulin variants and membrane proteins. Vydac 219TP is suitable for polypeptides with aromatic side chains, large hydrophobic proteins, membrane-spanning peptides, lipid peptides and fusion proteins from inclusion bodies.

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.
