Patent number: 9885692Abstract: The invention concerns a method for producing a chromatography-enrichment column, the method comprising the following steps: (a) depositing at least one layer of desired particles, which may be identical or different, and are intended to constitute the stationary phase, in a compact assembly, on the flat surface of a substrate; (b) crosslinking the layer in at least the regions corresponding to the desired shape of the enrichment column to be obtained; (c) impregnating the layer with a light radiation-sensitive material; (d) insolating the layer obtained in step (c) so as to form insolated regions of which the shape corresponds to the desired internal shape of the enrichment column, if the light radiation-sensitive material behaves like a positive resin or to form non-insolated regions of which the shape corresponds to the desired internal shape of the enrichment column if the light radiation-sensitive material behaves like negative resin; and (e) eliminating the light radiation-sensitive material in the zoneType: GrantFiled: July 2, 2013Date of Patent: February 6, 2018Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventors: Olivier Dellea, Pascal Fugier, Helene Marie, Severine Vignoud

Patent number: 9228955Abstract: Provided is a system for detecting analytes of interest present in a gas sample, including a layer of porous material, positioned at the surface of a substrate so as to extend longitudinally along a fluidic flow path of the gas sample, said porous material containing a plurality of probe molecules, each probe molecule being able to react with the analyte of interest by causing a change in the spectral properties of said probe molecule. Also included is a a pump for generating a flow of the gas sample along the fluidic path so that the gas sample comes into contact with said layer of porous material. The system also includes at least one optical detection device capable of successively detecting, at distinct detection areas of said porous material layer distributed along said fluidic path, a change in the spectral properties of at least one of said probe molecules.Type: GrantFiled: August 26, 2011Date of Patent: January 5, 2016Assignee: Commissariat a l' energie atomique et aux energies alternativesInventors: Severine Vignoud, Michael Descamps, Francois Perraut, Anne Planat-Chretien, Emmanuelle Schultz
