A method for detecting the composition of an unknown gas mixture (M inc) through an electronic nose (2) equipped with a measuring chamber (3) that houses at least one sensor comprises the steps of: calibrating a sensor by feeding a known gas mixture (M n) into the measuring chamber (3); feeding the unknown gas mixture (M inc) into the chamber (3), while keeping the unknown gas mixture (Mine) in a predetermined desired state; and detecting the composition of the unknown gas mixture (M inc) by means of the sensor.

Procédé de détection de la composition d'un mélange gazeux inconnu (Minc) à travers un analyseur d'odeurs (2) équipé d'une chambre de mesure (3) qui loge au moins un capteur. Ledit procédé comprend les étapes consistant à : calibrer un capteur en acheminant un mélange gazeux connu (Mn) dans la chambre de mesure (3) ; acheminer le mélange gazeux inconnu (Minc) dans la chambre (3), tout en maintenant le mélange gazeux inconnu (Minc) dans un état voulu prédéterminé ; et détecter la composition du mélange gazeux inconnu (Minc) au moyen du capteur.
