Summary
A new way to produce liquid chromatographic stationary phases is suggested. The method is based upon a solide-phase reaction between the silica surface and the adsorbed silane molecules. The role of surface pH is demonstrated. The influence of other reaction conditions (concentration of the silane solution, effect of temperature and reaction time) is discussed.
