HPLC Guard Columns and Cartridges
YMC America, Inc Ph-HG guard 120A 10um 10x4mm
Phenyl columns provide unique selectivity when compared to aliphatic straight chain reversed phase materials such as C18 C8 and C4 YMC-Pack Phenyl is a monomerically-bonded phenyl and is fully endcapped Typical applications include aromatic compounds phenols fullerenes sweeteners
YMC America, Inc C8-HG guard 300A 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
