Chemically bonded stationary phases for use in liquid chromatography can be prepared by the reaction between appropriate silane monomers or partially polymerized silanes and functional groups on the surface of chromatographic support materials. Methods reported so far mostly concern the preparation
An alternative to the well known reversed-phase separations on chemicallybonded phases has been developed. The approach is based on a dynamic modification of bare silica with long chain quaternary ammonium ions. The influence of the concentration and type of the quaternary ammonium ion, the pH value
