Abstract: A method for characterizing an analyte A present in a gas sample using an electronic nose including M sensitive site, a parasitic chemical species P being present in the gas sample, the method include: a phase 100 of acquiring N first signatures, where N>1, of the gas samples containing the analyte A and the parasitic species P, the gas samples exhibiting deviations ΔcP(n) which differ from one gas sample to the next; a phase 200 of solving an optimization problem so as to obtain N corrected signatures, characterising the analyte A present in the N gas samples, from the N first signatures, by optimizing to objective functions.
