Mac-Mod Fortis Prep 30.0 mm Guard Holder
Fortis HPLC and UHPLC columns are packed with 100 A high-surface area silica-based columns designed with optimized bonding chemistries for uniform ligand coverage. This proprietary process improves method development and improves LCMS sensitivity by eluting compounds in higher organic mobile phases, as well as when scaling to preparative separation elutions in higher organic leads to quicker dry-down times. C18, C8, Diphenyl, H2o, Cyano and Amino bonded phases are all available on 1.7, 3, 5 and 10 um particle sizes. HILIC and DIOL phases are also available in the Fortis HILIC range. Fortis columns are available in a wide range of column IDs and column lengths including 75 micron, 200 micron, 2.1, 3.0, 4.6, 10 and 21.2 mm ID columns other column IDs and lengths available upon request. Guard columns are available and require guard holder DCGUA1.

Mac-Mod Evosphere C18/PFP, 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.
