	2	Hydride-Based Separation Materials for High Performance Liquid Chromatography and Open Tubular Capillary Electrochromatography显示文摘Silica hydride is a recent development in chromatographic support materials for high performance liquid chromatography(HPLC) where hydride groups replace 95% of the silanols on the surface.This conversion changes many of the fundamental properties of the material as well as the bonded stationary phases that are the result of further chemical modification of the hydride surface.Some unique chromatographic properties of hydride-based phases are described as well as some general application areas where these bonded materials may be used in preference to or have advantages not available from typical stationary phases.The fabrication,properties and applications of etched chemically modified capillaries for electrophoretic analysis are also reviewed.It is shown that the etching process creates a surface that is fundamentally different than a bare fused silica capillary.The new surface matrix produces unique electroosmotic flow properties and is more compatible with basic and biological compounds.After chemical modification of the surface,the bonded organic moiety(stationary phase) contributes to the control of migration of solutes in the capillary.Both electrophoretic and chromatographic processes take place in the etched chemically modified capillaries leading to a variety of experimental variables that can be used to optimize separations.A number of examples of separations on these capillaries are described.
