Abstract: A chromatography method in which a gaseous, liquid or supercritical mobile phase containing species to be separated is circulated through a packing. The packing includes 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. A continuous medium permeable to molecular diffusion extends between the ducts, including a porous organic gel or an organic liquid with at least one network of connected pores, the size of which is greater than two times the molecular diameter of at least one species to be separated. The at least one species has a diffusive path between the ducts.
