Abstract
The invention concerns a method for producing a chromatography analysis column, the resulting column, and a device comprising such a column. The method according to the invention comprises the following steps: (a) depositing on the flat surface of a substrate a first layer of particles which are intended to form the stationary phase; (b) depositing on the layer at least one second layer of compactly assembled particles; (c) impregnating the first and second layers with a light radiation-sensitive material, to form at least two compactly assembled particle layers impregnated with sensitive material; (d) insolating these layers in the regions corresponding to the desired internal shape of the chromatography analysis column, if the light radiation-sensitive material behaves like a positive resin, or outlining this internal shape if the light radiation-sensitive material behaves like a negative photosensitive resin; (e) eliminating either the regions insolated in step (d) if the light radiation-sensitive layer behaves like a positive photosensitive resin, or the regions not insolated in step (d) if the light radiation-sensitive material behaves like a negative photosensitive resin; and…
