HPLC Columns
Mac-Mod Evosphere C18/PFP, 100 Å, 3 µm, 0.3 x 100 mm Monodisperse Fully Porous Particle HPLC Column
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 MAC-MOD Chiral Im-Amy-3, 5 µm, 21.2 x 250 mm Immobilized SFC/HPLC Column
MAC-MOD Chiral HPLC, UHPLC and SFC Chiral Columns are an exciting range of Amylose or Cellulose coated Reversed-Phase or Normal Phase columns proud to be manufactured in the USA. These columns should be your first choice when scouting new selectivity options to improve resolution of racemic enantiomeric mixtures. These columns are also an excellent choice to compare with current Chiral column offerings to see if novel bonding and packing methods can improve resolution. MAC-MOD Chiral columns offer a wide range of novel chiral selectors as well as similar chiral selectors to industry standard chiral columns. However, all chemistries should be tried to ensure proper screening of chiral selectors due to proprietary silica manufacturing and packing mehtods that may still deliver increased resolution to industry standard comparisons.

Mac-Mod Avantor Prevail C18, 110 Å, 3 µm, 4.6 x 150 mm HPLC Column
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.
