Abstract
The invention relates to a stationary phase medium for adsorption chromatography, which is in form of porous particles suitable for being packed into a chromatographic column. The porous particles are made of cross-linked polymeric material and formed with interconnected macropores to constitute a porous network, through which a mobile phase fluid may flow in a convective manner. The porous particles are substantially free of diffusive pores and, thus, the mass transfer through the porous network is governed by convection alone. The porous particles are fabricated to have irregular granular configurations with rough outer surfaces, so that the convective flow between the porous particles will not be impeded during chromatography process.
