Abstract
Polymer-coated carbon-clad inorganic oxide particles are disclosed which are useful in sorbent applications, particularly as packing materials for High Performance Liquid Chromatography (HPLC). A method for the preparation of a chromatographic support material is also disclosed which comprises coating carbon-clad inorganic oxide particles with a monomer or oligomer and cross-linking the monomer or oligomer.
Claims31
A particle comprising an inorganic oxide core, a carbon cladding on said core, and a cross-linked polymer coating on said carbon cladding, wherein said inorganic oxide core has a diameter of about 1.mu. to about 1 cm.
A particle comprising an essentially non-porous inorganic oxide core, a carbon cladding on said core, and a crosslinked polymer coating on said carbon cladding.
