Abstract (en)
[origin: WO2022189292A1] The invention relates to a method for characterizing an analyte A present in a gas sample using an electronic nose comprising M sensitive sites, a parasitic chemical species P being present in the gas sample, comprising: o 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 Δc p(n) which differ from one gas sample to the next; o a phase 200 of solving an optimization problem so as to obtain N corrected signatures, characterizing the analyte A present in the N gas samples, from the N first signatures, by optimizing two objective functions.
