Mac-Mod Enantiocel Chiral A2, 5 um, 4.6 x 250 mm Column
ColumnTek Enantiocel 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. ColumnTek EnantioCel 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.
YMC America, Inc Amyl-SA col 3um 50x2mm
YMC s CHIRAL ART series features polysaccharide-derived chiral stationary phases (CSPs) based on amylose and cellulose tris-carbamate derivatives available in both coated and immobilized formats These columns provide exceptional stereoselectivity durability and solvent versatility supporting normal-phase reversed-phase and supercritical fluid chromatography (SFC) modes
YMC America, Inc ODS-AQ Actus 120A 5um 250x30mm
YMC-Pack ODS-AQ is a unique reversed-phase material with both a hydrophobic high carbon loading and a relatively hydrophilic surface Because of the hydrophilic surface ODS-AQ can be wetted with polar eluents It provides chromatographers reproducible retention and excellent peak shape in highly aqueous mobile phases including 100% water This is due to the C18 ligands on ODS-AQ actually being lifted from the surface by the action of the eluents penetrating the silica pores Selectivity on YMC-Pack ODS-AQ can be subtly different from that seen on conventional ODS columns Differences in selectivity are most often encountered when analyzing mixtures of relatively polar compounds Typically longer retention and greater resolution are observed with ODS-AQ Available in both 120 and 200 pore sizes YMC-Pack ODS-AQ is well-suited for analysis and purification of peptides and other biomolecules
YMC America, Inc Tri BioC4 300A 3um 150x2.1mm
YMC-Triart phases are based on organic/inorganic hybrid particles that combine the high mechanical stability and efficiency of a silica-based packing material with the robust chemical stability of a polymer-based packing material This versatile resin is produced using tightly controlled particle formation technology adapted from micro-reactor technology The resulting uniform particle and pore size distributions as well as the smooth surface greatly contribute to excellent peak shape and separation reproducibility In addition YMC-Triart materials are highly resilient and robust when used at extreme pH elevated temperature and high pressure
