Abstract
A series of mixed chemically bonded phases, which contained alkylamide and aminopropyl ligands, were prepared by subsequent reaction of the silica-based aminopropyl phase with suitable alkanoyl chlorides. Physicochemical properties of these phases were studied by using various techniques such as elemental analysis, 29Si and 13C solid-state NMR and adsorption.
In addition, suitable chromatographic measurements were carried out in order to study the effect of the length of the terminal alkyl chain on the solute's retention under reversed phase conditions.
