Over the last decade sol-gel organic-inorganic hybrid materials have attracted significant interest of the separation science community. Surface-bonded sol-gel organic-inorganic stationary phases and extraction media can be prepared under extraordinarily mild thermal conditions. They are characterized by enhanced material stability. An overview of the development of sol-gel stationary phases and extraction media will be presented covering preparation, characterization, applications, and advantages of silica- and nonsilica-based sol-gel coatings [1-4] and monolithic beds [5] in various separation and sample preconcentration techniques (References : 1 .
