HPLC Guard Columns and Cartridges
WELCH MATERIALS INC Ultisil XB-C18, Semi-Prep Cartridge: 5µm, 120Å, 10×10mm
Welch preparative guard column cartridges use the same packing as the preparative column, which can intercept some of the same polar substances in the sample and prevent them from contaminating and damaging the packing materials in the preparative column. 10×10mm cartridge holder: 00808-01116, 21.2×10mm cartridge holder: 00808-01106, 30×10mm cartridge holder: 00808-01117, 50×10mm cartridge holder: 00808-01110.Ultisil XB-C18 is one of the most versatile C18 analytical columns on the market. It features advanced bonding and double-endcapping technology, delivering nearly perfect peak shapes. This column is ideal for analyzing complex matrix samples and provides excellent peak shapes for acidic and basic compounds. It is particularly effective for the separation of traditional Chinese medicine compounds.

XTerra MS C8 VanGuard Cartridges are used to extend analytical column lifetime and performance by removing particulate contamination from the mobile phase stream. This cartridge is optimized to protect all 2.1 mm and 3.0 mm I.D. XTerra MS C8 analytical columns containing 3.5 µm sorbent particles.
Sepax Technologies Inc Sepax HPLC Column Proteomix SCX, NP5, Guard cartridge with 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 Evosphere C12, 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.
