| abstract |
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. |
