Sorption and selective properties of the composite sorbent based on aggregated nano-sized
particles of silicon dioxide, modified with a mixture of liquid crystal 4-n-octyloxy-4'-cyanobiphenyl and
chiral macrocyclic geptakis-(2,3,6-tri-O-acetyl)-β-cyclodextrin. It is shown that the investigated sorbent is
selective with respect to the structural and optical isomers. The separation properties explored in terms of
adsorption and absorption of gas chromatography on silica capillary column type SCOT, made the
original method based on aerosol-gel transition
