A detection system for an electronic nose which allows a physicochemical classification of odors, that is to say a classification as a function of the physicochemical properties of the volatile compounds, or odorous molecules, making up these odors. This detection system comprises sensors with cross-reactivity with respect to volatile compounds, each sensor comprising a sensitive part functionalized by a receptor comprising a sequence formed by the repetition of an α-amino acid. The α-amino acid of the receptor of a sensor of a first series of sensors is hydrophilic, while the α-amino acid of the receptor of another sensor of the first series is hydrophobic, and the α-amino acids of the receptors of two sensors of a second series of sensors have isoelectric points which differ from one another by at least one pH unit.

The invention relates to a detection system for an electronic nose capable of detecting and identifying a set of compounds that can be found in a gaseous sample, the detection system comprises a plurality of cross-reactivity detection sensors (D, D, D, D, D, D, D) for supplying signals representing the presence of one or more compounds of said set in the gaseous sample, and which is particularly characterised in that the detection system further comprises at least one reference sensor (RI) for supplying a signal representing the measurement noise of the detection system. The detection system further relates to an electronic nose comprising such a detection system.
