Abstract

Using a modified Stöber method, monodisperse silica microspheres with average diameters from 1 μm to 2 μm are synthesized as UPLC column fillers. With a column as short as 50 mm, the 1.5 μm C18-modified silica stationary phase can separate C60 and C70 in 7 minutes with ultra high efficiency.
