YMC America, Inc C8 120A 3um 75x0.5mm 1/32
YMC-Pack C8 columns are prepared using exhaustive bonding of a monomeric octylsilane to totally porous and spherical silica gels The functionalized silica is then treated with an endcapping process which produces a moderate 10% carbon loading on the standard 120 pore material Available in three pore sizes YMC-Pack C8 columns will separate many classes of compounds including pharmaceuticals organic chemicals and biologics
YMC America, Inc CN 120A 5um 150x0.075mm 1/16
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 ProC4 120A 3um 150x0.1mm 1/16
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 The wide pore butyl chemistry allows minimal distortion of tertiary conformation for large biomolecules and results in samples that are pure concentrated and high in biological activity
YMC America, Inc TMS 120A 5um 100x0.3mm 1/16
YMC-Pack TMS columns are bonded with trimethylmonochlorosilane to create a phase with intermediate polarity This makes for a versatile stationary phase that is useful for analysis of extremely hydrophobic compounds using conventional reversed-phase solvents or highly polar compounds using high aqueous solvents The unique chemistry of this packing material is also well-suited for the analysis of multifunctional compounds Selectivity characteristics of a C1 bonded phase can be unique and samples must be evaluated to determine the applicability of the phase
YMC America, Inc Triart C18 120A 5um 250x3mm
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 Jsphr L80 80A 4um 50x.3mm 1/16
The J sphere series of columns consists of three kinds of ODS made from the same silica gel base each with a different ligand coverage The 4 um 80 silica support provides outstanding chromatographic efficiency while the high surface area material (500 m2/g) offers exceptional interaction with analytes This combination provides excellent peak symmetry across all J sphere products The variations in ligand coverage produce three columns with different hydrophobicity hydrogen bonding capacity and steric selectivity for tertiary structures Because of this J sphere can be used with confidence to identify structural differences of solutes and to improve the efficiency of separation optimization
YMC America, Inc Triart C18-S 120A 7um 250x10mm
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
