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.
