HPLC Guard Columns and Cartridges
Mac-Mod Evosphere AQ, 100 Å, 5 µm, 30.0 x 10 mm Monodisperse Fully Porous Particle Guard Cartridge
Evosphere UHPLC and HPLC columns are 100 A Monodispersed Fully Porous Silica-based columns designed to combine the benefits of Fully Porous and Core-Shell particle technology into an improved particle design and morphology that brings cutting-edge loading capacity to ultra-high-resolution particle columns. The Monodispersed Particles provide similar efficiency to Core-Shell products when comparing them directly via particle size matching and significantly increase loadability which allows ultra-high resolution analytical separations to scale to preparative separations for isolation work if needed. The bonded phase chemistries are exciting as well to maximize selectivity with novel C12 bonded phase, 2 multi-modal C18/AR, and C18/PFP bonded phases, an extended and stabilized phenyl funtionality in the Diphenyl bonded phase, a polar endcapped AQUA phase, a Phenyl-Hexyl phase, a propyl PFP phase and the RP18-Amide bonded phases which is great for doing bases at low pH.
Waters Corp XTerra MS C18 Prep Guard Cartridge, 125Å, 5 µm, 7.8 mm X 10 mm, 1/pk
XTerra Prep columns bring the benefits of Hybrid Particle Technology to isolation and purification applications in discovery and development laboratories. XTerra Prep MS columns possess our patented Hybrid Particle Technology, with particles engineered specifically for prep. It allows you to routinely operate at pH 1-12 so you can load up to 60X more onto the column. More capacity results in fewer injections for the same amount of pure material or more material with the same number of injections. In the discovery world, this greater capacity means you can use a shorter column, producing the same amount of material in half the time.
Waters Corp XBridge BEH Shield RP18 Sentry Guard Cartridge, 130Å, 5 µm, 3 mm X 20 mm, 2/pk
XBridge BEH Shield RP18 columns complement the XBridge BEH C18 and C8 phases and provide a necessary and powerful tool for HPLC method development. The embedded carbamate group in the bonded phase ligand provides alternate selectivity, especially for phenolic compounds compared to straight chain alkyl columns.

Optimize Technologies EXP Trap Cartridge, 1mm x 5mm, 3.0µm EXP, 3.0µm EXP, Phenyl-Hexyl, 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.
