Abstract
The invention discloses a composite material comprising a deformable gel retained within the pores of a porous rigid support material. The deformable gel comprises an affinity chromatography agent such that the composite material has affinity chromatography properties.
Claims9
A particulate material comprising a plurality of discrete porous rigid support particles, and a deformable xerogel retained within and substantially filling the pore structure of the support particles, said deformable xerogel comprising an affinity chromatography agent such that the particulate material is a composite material having affinity chromatography properties.
A method for preparing a particulate material comprising a deformable xerogel retained in the pore structure of a particulate porous rigid support material which comprises introducing a precursor for the xerogel into the pore structure of a plurality of discrete particles of porous rigid support material such that the gel precursor fills the pores of the discrete particles, and effecting gelation of the precursor within the discrete particles to form a plurality of discrete porous rigid support particles having a deformable xerogel retained within and substantially filling the pore structure of the support particles, said deformable xerogel having affinity chromatography properties.
