Abstract: A method for recalibrating an electronic nose includes successively injecting, into a measurement chamber, reference gases that do not contain target compounds and that have various values of relative humidity. A measurement signal is determined in the course of each injection. Then, for each reference gas, a baseline is determined, which baseline is representative of the determined measurement signal. The baseline is also associated with the relative humidity of the reference gas present. A second correction function is determined on the basis of the determined baselines and of the predetermined values of relative humidity. The second correction function is then stored in a processing unit instead of a first correction function.

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.
