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 Waters XBridge Premier BEH C8 VanGuard FIT Column, 2.5 μm, 4.6 mm X 150 mm
The XBridge Premier BEH C8 Columns provide less retention than C18 columns, facilitating rapid method development. They leverage trifunctionally bonded BEH particles for a broad pH range (1 to 12), excellent low pH stability, and minimal column bleed, alongside MaxPeak High Performance Surface hardware to enhance peak shape and signal intensity. The VanGuard Fit design extends column lifespan by protecting against contaminants.
- Less retentive compared to C18 columns, which is desirable for fast method development.
- Trifunctionally bonded BEH particles offer the widest usable pH range (1 to 12), superior low pH stability, and ultra-low column bleed.
- MaxPeak High Performance Surface hardware technology significantly reduces unwanted analyte/surface interactions, improving peak shape and signal intensity.
- VanGuard Fit column design protects the column from contaminants and increases column lifetime.
