Microsolv Technology Corporation HPLC Column, HPS C18, 5um, 2.1mm ID x 50mm Length, 120A. 1 EA.
This Cogent HPS C18™ Stationary Phase has been a premium value and used by HPLC laboratories for many years. It is double end capped ( fully ), with mono functional bonding of an 18 carbon silane to our unique silica, making this Column ideal as an Alternate in any USP Method that uses the L1 Classification or for new methods. With a 5 µm Particle, this column works well with higher flow rates and lower back pressures compared with smaller particles. Used for hydrophobic or neutral compounds in Reversed Phase, this Octadecyl Phase is excellent for long chain fatty acids. Expect longer retention than with a C8 column. Compare to Inertsil™C18 and Luna™ C18 brand columns. A very popular column size, this short and narrow-bore column provides short run times but requires a pump that can precisely deliver, and a flow cell that is made for, reduced flow rates with lower volumes. This column size is excellent, and a favorite for LCMS.
Mac-Mod MAC-MOD Chiral Im-Cel-2, 5 µm, 3.0 x 150 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 Evosphere BIO INERT 300 Å, C18/AR, 5 µm, 3.0 x 150 mm Monodisperse Fully Porous Particle Column in Inert-Coated Hardware
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.
