    摘要: A new and useful structure for forming a capillary tube (10), e.g. for gas chromatography, and a technique for forming the capillary tube (10) is described. The capillary tube (10) comprises a tube structure (12), and a deactivated surface-bonded sol-gel coating (14) on a surface (16) of the tube structure (12) to form a stationary phase coating (14) on that surface (16) of the tube structure (12). According to the present invention the deactivated stationary phase sol-gel coating (14) enables separation of analytes while minimizing adsorption of analytes on the separation column structure (12).
