摘要
Novel chromatographic materials for chromatographic separations, columns, kits, and methods for preparation and separations with a superficially porous material comprising a substantially nonporous core and one or more layers of a porous shell material surrounding the core. The material of the invention is comprised of superficially porous particles and a narrow particle size distrution. The material of the invention is comprised of a superficially porous monolith, the substantially nonporous core material is silica; silica coated with an inorganic/organic hybrid surrounding materia; a magnetic core material; a magnetic core material coated with silica; a high thermal conductivity core material; a high thermal conductivity core material coated with silica; a composite material; an inorganic/organic hybrid surrounding material; a composite material coated with silica; a magnetic core material coated with an inorganic/organic hybrid surrounding material; or a high thermal conductivity core material coated with an inorganic/organic hybrid surrounding material.
