Popis: Silica whiskers were grown on the inside of an open-tubular glass capillary column according to a modified version of Schieke's method. The surface of the silica whiskers was modified by reaction with a flowing solution of octadecylsilyl trichloride and hexamethyl-disilazane, then with a mixture of trimethylchlorosilane and hexa-methyldisilazane. The whiskers grown and the surface modifications were examined with a scanning electron microscope and an electron microprobe X-ray analyser. Finally, the chemically bonded glasswhisker columns thus prepared were evaluated with mixtures of hydrocarbons, fatty acid methyl esters andn-alcohols under isothermal or programmed-temperature conditions.
