Abstract: Chromatography method in which a gaseous, liquid or supercritical mobile phase containing species to be separated is circulated through a packing, said packing being characterized in that: —it comprises a plurality of capillary ducts extending in the packing between an upstream face through which the mobile phase enters the packing and a downstream face through which the mobile phase leaves the packing—the material of the walls comprises a first population of connected pores, providing passages from one duct to the next enabling molecular diffusion to take place between adjacent ducts, pores having a mean diameter (dpore) of greater than 2 times the molecular diameter of at least one species to be separated—the diameter of the ducts is less than 50 μm.

Abstract: The invention relates to a monolithic porous material based on amorphous silica or activated alumina or on one of their mixtures, the material comprising substantially rectilinear capillary ducts that lie parallel to one another, and being intended to be used as packing in a chromatography column, characterised in that: the ducts have, relative to one another, a substantially uniform cross section; the cross-section of each duct is uniform over its entire length; the ducts pass right through the material; the volume of micropores smaller than 0.3 nm is smaller than 50% of the total porous volume of the material.

Abstract: The invention relates to a monolithic porous material made of amorphous silica or activated alumina, comprising substantially rectilinear capillary channels that are parallel to one another, wherein: the channels have a substantially uniform cross-section relative to each other, the cross-section of each channel is regular over its entire length, the channels pass through the material from end to end, the length of the channels is equal to or more than 10 mm. The invention also relates to an annular, radial or axial chromatographic apparatus, the packing of which consists of at least one said monolithic material.The invention also relates to processes for manufacturing such a monolithic material.
