YMC America, Inc C8 guard 120A 10um 10x4mm
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 C8-HG guard 300A 10um 50x30mm
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 SIL-HG guard 120A 20um 50x30mm
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 C8-HG guard 120A 15um 50x30mm
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 C8-HG guard 120A 20um 50x20mm
