Mac-Mod Evosphere RP18-Amide, 100 Å, 5 µm, 21.2 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.
Mac-Mod Avantor ACE UltraCore SuperPhenylHexyl, 95 Å, 4.6 x 5 mm UHPLC Guard Cartridges (3/pk)
Avantor ACE UltraCore solid-core (core-shell) particle columns are ideal for MS work offering improved signal intensity and maximum response. These columns combine high efficiency separations with low back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability. Solid Core particle technology provides higher efficiencies per unit back pressure as compared to sub-2-micron UHPLC columns. Columns combine the proven advantages of UHPLC and HPLC columns with Solid Core Particle Technology. Solid-core columns can be used on both UHPLC and HPLC systems. Excellent peak shape and phases stability with extended pH. Highly inert, ultra-low bleed, designed for use with LC/MS compatible buffers. 2.5 and 5 µm particle sizes available.
