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.
Claims51
A chromatography column selected from the group consisting of a liquid chromatograph column, a gas chromatography column and a supercritical fluid chromatography column, comprising a packing consisting of a plurality of particles comprising an inorganic oxide core, a carbon cladding on said core, and a cross-linked polymer coating on said carbon cladding contained within said column.
An absorber selected from the group consisting of a batch adsorber, a fluidized bed adsorber and a pressure-swing adsorption apparatus, comprising an adsorptive medium consisting of a plurality of particles comprising an inorganic oxide core, a carbon cladding on said core, and a cross-linked polymer coating on said carbon cladding contained within said absorber.
A reactor selected from the group consisting of a fixed bed reactor, a fluidized bed reactor and a batch reactor, comprising a support material consisting of a plurality of particles comprising an inorganic oxide core, a carbon cladding on said core, and a cross-linked polymer coating on said carbon cladding contained within said reactor.
