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 (f) covering and sealing the structure obtained in step (e) with a cover covered on the face facing the layers with at least one layer of compactly assembled particles which are identical to or different from those deposited on the substrate surface. The invention is used in particular in the field of chemical analysis.
