YMC America, Inc SIL 120A 5um 50x0.3mm 1/32
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 TriPFP 120A 5um 150x.075mm1/16
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

YMC America, Inc C4 200A 5um 5x0.3mm 1/32
YMC-Pack C4 is ideal for analyzing mixtures with a wide range of component polarity This is due to the C4 bonded phase exhibiting shorter analysis time while still maintaining high resolution when compared to longer-chain bonded chemistries YMC-Pack C4 (Butyl) columns are available with three pore sizes to accommodate optimum separations of virtually any molecular-weight compound The 120 phase is used extensively with non-polar peptides which are too strongly retained on C8 and C18 The 200 and 300 phase columns effectively resolve many classes of proteins and biopolymers
YMC America, Inc ODS-AQHG 120A 20um 500x30mm
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
