A soft and long C18 alkyl chain was coupled onto silica（Sinopak-S, particle size d=5 μm, pore diameter Dp=11 nm; and surface area S=170 m2/g） with γ-glycidoxypropyltrimethoxysilane as coupling agent. Chromatographic evaluation indicate that its reversed phase behavior was similar to ordinary ODS.展开更多
文摘A simple, practical and economical procedure has been developed to prepare novel C18 ether-bond reversed phase packing. A soft and long C18 alkyl chain was coupled onto silica（Sinopak-S, particle size d=5 μm, pore diameter Dp=11 nm; and surface area S=170 m2/g） with γ-glycidoxypropyltrimethoxysilane as coupling agent. Chromatographic evaluation indicate that its reversed phase behavior was similar to ordinary ODS.
