摘要

A simple one-step process was used to synthesize uniform,spherical organosilica nano-particles containing octadecyl moieties.These nano-particles,having a diameter of 670 nm,were slurry packed into fused-silica capillarytubes of 50 #mu#m internal diameter and tested for sue in ultrahigh-pressure liquid chromatography at inlet pressures of about 50,000 psi,providing for the use of HPLC with nano-particle packed columns.The retention characteristics of a column packed with the organo-nano-particles were shown to be stable under acidic and basic conditions.Fast analysis times and relatively high separation efficiencies were obtained under the conditions used.
