YMC America, Inc C4 guard 200A 3um 10x4mm
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 TMS guard 120A 5um 10x4mm
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 CN-HG guard 120A 20um 50x20mm
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 C8-HG guard 120A 10um 50x20mm
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
