Small density microporous solid substance carrier materials, their preparation and their use for the cleaning of large of macromolecules and bioparticles

摘要

The present invention provides small, dense mineral oxide solid supports or microbeads, comprising dense microporous mineral oxides matrices in which a skin of polymers is rooted, and their use in downstream processing, especially for fluidized bed purification of bioparticles or high molecular weight macromolecules.
