Abstract

See full text

Novel particles and materials for chromatographic separations, processes for preparation and separations devices containing the chromatographic particles and materials are provided by the instant invention. In particular, the invention provides a porous inorganic/organic hybrid particle, wherein the inorganic portion of the hybrid particle is present in an amount ranging from about 0 molar % to not more than about 49 molar %, wherein the pores of the particle are substantially disordered. The invention also provides a porous inorganic/organic hybrid particle, wherein the inorganic portion of the hybrid particle is present in an amount ranging from about 25 molar % to not more than about 50 molar %, wherein the pores of the particle are substantially disordered and wherein the particle has a chromatographically enhancing pore geometry (CEPG). Methods for producing the hybrid particles, separations devices comprising the hybrid particles and kits are also provided.
