YMC America, Inc NH2 guard 120A 5um 10x3mm
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 Triart C18 grd 120A 5um 20x3mm
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 ProC4 guard 120A 5um 10x3mm
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 ODS-AL guard 120A 5um 20x3mm
YMC-Pack ODS-AL is a non-endcapped high carbon load monomeric C18 phase It exhibits different selectivity from conventional ODS columns due to the use of not only hydrophobic interaction but also secondary interactions caused by silanol groups YMC-Pack ODS-AL is intended for use only in those situations where residual silanol activity is beneficial to the separation
YMC America, Inc ODS-AL guard 120A 3um 20x2.1mm
