  Abstract:  The surface modification of Romanian silica gel sample was performed by organosilanization reaction with 3-mercaptopropyltrimethoxysilane. The obtained stationary phase was investigated by 29Si and 13C CP/MAS NMR and FTIR spectroscopic solid-state techniques in order to put in evidence the presence of the modifier and the variety of bonded silyl species on the surface as well as to find out the modifier effect on the surface properties.
