Waters XSelect Preparative Column, CSH C18, 10 μm, 130 Å, 50 x 50 mm
YMC America, Inc HS C18 120A 5um 100x.5mm 1/16
Hydrosphere C18 is based on highly inert ultra-pure pH neutral silica and is designed to maintain a hydrophilic surface for superior separation of hydrophilic compounds Minimal metal content and very low concentrations of residual silanols make this an ideal phase for the analysis of basic pharmaceuticals and chelating compounds even under LC-MS conditions such as separation in non-phosphate buffered systems In addition the ability to separate polar compounds under highly aqueous mobile phase conditions without loss in retention plate counts and peak performance greatly enhances the versatility of Hydrosphere C18
YMC America, Inc CN 300A 5um 5x0.5mm 1/32
YMC-Pack CN can be used for both normal phase and reversed phase analyses due to the medium polarity of the cyanopropyl phase bonded to the silica base particle It can be used in normal phase with low-polarity mobile phases such as hexane or in reversed phase with highly-polar mobile phases such as methanol and water YMC-Pack CN can be useful for shortening analysis time in situations where retention is substantial using C18 or C8 or when separation optimization is difficult
YMC America, Inc SIL 120A 3um 100x0.3mm 1/16
The high-purity silica found in YMC-Pack SIL columns provides virtually complete sample recovery The absence of silica impurities reduces non-specific sample adsorption and the totally porous nature of the silica provides high sample loading The elevated chemical purity of YMC silica results in a particle structure exhibiting high mechanical strength YMC-Pack SIL is suitable for separation of fat-soluble compounds using non-polar mobile phases as well as the separation of positional isomers that are difficult to separate in reversed-phase mode SIL-06 (60 pore size) has greater adsorption properties than SIL (120 pore size) due to its larger surface area and is generally useful for separating natural products with low molecular weight
YMC America, Inc ODS-AQHG 120A 10um 250x4.6mm
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 NH2-HG col 120A 10um 125x4mm
YMC-Pack NH2 is a normal phase separation column utilizing the polarity of primary amino groups bonded to silica It is a versatile stationary phase often used for the separation of sugars but can also be used for separations utilizing weak anion-exchange
YMC America, Inc Tri Ph 120A 3um 100x.5mm 1/32
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

Mac-Mod MAC-MOD Chiral Cel-4, 5 µm, 3.0 x 100 mm HPLC Column, for Normal-Phase or SFC Use
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.
