Patent ID: 7291383

Claim:
A support for solid phase extraction, comprising: a ceramic elongate honeycomb substrate having a plurality of holes formed therein, each said hole having a diameter defined by a distance between diametrically opposed points on an inner wall surface facing said at least one hole, said diameter of each said hole being less than or equal to 1 mm; and an inorganic porous material filling said at least one hole, said inorganic porous material being produced by sol-gel transition accompanied by phase transition; wherein said elongate honeycomb substrate comprises one of silicon oxide, aluminum oxide, titanium oxide, zirconium oxide, cordierite, silicon carbide and silicon nitride; wherein said porous material comprises one of silicon oxide, titanium oxide, zirconium oxide and alumina; and wherein each said hole has a longitudinal extension axis that is parallel to a longitudinal extension axis of said elongate honeycomb substrate, said longitudinal extension axis of each said hole being substantially continuous along said longitudinal extension axis of said elongate honeycomb substrate between first ends of said holes and opposed second ends of said holes.
