HPLC Guard Columns and Cartridges
YMC America, Inc ProC8 guard 120A 5um 10x3mm
YMC-Pack Pro C8 columns are made using advanced endcapping technology to reduce residual silanol activity This results in excellent peak shapes for basic compounds In addition the ultra pure silica and very low residual silanol activity means that these columns frequently do not require the use of ion-pairing reagents or ion-suppression techniques making them ideal for LC/MS applications Surface hydrophobicity is lower than that of ODS making Pro C8 useful for fast analysis of compounds of greatly differing hydrophobic properties Pro C8 can also be useful for separation of hydrophilic and planar compounds in cases where resolution is hard to achieve on ODS materials
Waters Corp Atlantis VanGuard Cartridge, HILIC, Silica, 100Å, 3 μm
Atlantis HILIC VanGuard Cartridges extend the lifetime and performance of analytical columns by removing particulate contamination from the mobile phase.

Mac-Mod Avantor Prevail C8, 110 Å, 5 µm, 4.6 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 Evosphere C18/AR, 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.
