Abstract: A method for characterizing compounds of interest, introduced into a measuring chamber of an electronic nose, includes injecting a first gas sample formed from a carrier gas without the compounds of interest forming a second gas sample from the carrier gas with the compounds of interest; determining a measurement signal (Sk(ti)); measuring values φ1, φ2 of the relative humidity; determining corrective parameter ({tilde over (S)}kref|φ2; ΔSkref|Δφ); and determining a useful signal (Suk(tiϵP2)) by correcting the measurement signal associated with the second gas sample using the determined corrective parameter, and characterizing the compounds of interest based on the useful signal.

Abstract: A method for the qualitative and/or quantitative measurement of odors present in a chamber for transformation (cooking or fermentation) of a product makes it possible to prevent the measurement environment from contamination by measurement-interfering elements produced by the transformation and released in the chamber for transformation. The method makes use of a chamber for transformation, for example an oven, and of an electronic nose, pipes a fluidic system, and a removal chamber for removing the measurement-interfering elements. The method includes a measurement mode M and a cleaning mode N. The cleaning mode comprises the following steps: -N0- optionally, flushing the chamber for transformation, preferably by ventilating it; -N1- flushing the measurement chamber with a fluid, preferably ambient air; -N2- flushing the removal chamber with a fluid, preferably ambient air; and -N3- optionally, transferring at least a portion of the flushing fluid from the removal chamber into the chamber for transformation.

Abstract: The invention relates to a method for calibrating an electronic nose, said electronic nose comprising a plurality of optical sensors arranged on a surface and capable of being in contact with a gaseous medium of interest, said optical sensors being capable of delivering a signal representative of the local optical index of the gaseous medium of interest when they are excited by photons, the method being characterized in that it comprises the following steps: after having placed the electronic nose in a gaseous medium of interest at the initial pressure (P0) and the initial temperature (T0): a) sending photons in the direction of the sensors so as to excite said sensors; b) measuring the signal delivered by each of the sensors, this measurement providing as many responses as there are sensors; c) modifying the pressure and/or temperature of the gaseous medium of interest; d) repeating step b); and e) for each sensor, determining a correction factor such as a variation in the signal between steps d) and b) corrected by the correction factor either equal to or substantially equal to a variation in the signal between these same steps for a reference, said reference being provided by a reference sensor or a combination of reference sensors. Such a method allows a physical calibration, that in the present case is relative, to be performed between the different sensors.

Abstract: L'invention concerne un procédé de mesure qualitative et/ou quantitative d'odeurs présentes dans une enceinte de transformation (cuisson ou fermentation) d'un produit. Ce procédé permet de s'affranchir de la pollution du milieu de mesure par des éléments perturbateurs de la mesure qui sont produits par la transformation et libérés dans l'enceinte de transformation. Selon ce procédé, on met en œuvre une enceinte de transformation, par exemple four, un nez électronique, des conduits et un système fluidique, une chambre de prélèvement pour les éléments perturbateurs de la mesure. Ce procédé comprend un mode de mesure M et un mode de nettoyage N. Ce dernier comprend les étapes suivantes : -N0- éventuellement on purge l'enceinte de transformation de préférence en l'aérant; -N1- on purge la chambre de mesure avec un fluide, de préférence l'air ambiant; -N2- on purge la chambre de prélèvement avec un fluide, de préférence l'air ambiant; -N3- éventuellement, on transfère au moins une partie du fluide de purge de la chambre de prélèvement dans l'enceinte de transformation.
