ABSTRACT:
A support for solid phase extraction is provided for preventing the fracture of the porous body of the support and the space between the porous body and its container, and for processing various amounts of liquids to be processed while maintaining the ease of passage of liquid in use. The support for solid phase extraction comprises a ceramic substrate with one or more holes formed therein, and an inorganic porous material, filled in the hole or holes, which is produced by sol-gel transition accompanied by phase transition.
