Abstract
Selective monomolecular layers on siliceous surfaces used for the construction of high-resolution chromatographic columns are prepared by surface reactions with monohalogenated silanes, silazanes or silylamines, or monoalkoxy- or monoacetoxysilanes, and subsequent chemical modifications. Such monolayers form a basis for efficient films of chemically compatible stationary phases by introducing selective groups in gas-liquid chromatography and all forms of liquid chromatography, or for adsorbent modifications in gas-solid chromatography.
