The invention relates to a method and a device (16) for detecting volatile analytes in air samples, where a mass~sensitive sensor (20) with at least one sensor area (21) which is equipped with a surface layer with selective sensitivity for the analyte(s) to be detected is brought into contact with the air sample to be analyzed, the mass change of the surface layer is detected in the form of electrical signals and the electrical signals are evaluated. It is provided in accordance with the invention that the sensor signal is already evaluated at a point in time at which the maximum sensor signal for the analyte concentration in question is not yet obtained.

L'invention concerne une méthode et un dispositif (16) pour détecter des analytes dans des échantillons d'air, où un détecteur sensible à la masse (20) comportant au moins une zone de détection (21) qui est munie d'une couche superficielle à sensibilité sélective pour l'(les) analyte(s) à détecter, est mis en contact avec l'échantillon d'air à analyser. La variation de masse de la couche superficielle est détectée sous forme de signaux électriques et les signaux électriques sont évalués. Il est prévu, selon l'invention, que le signal du capteur soit d'ores et déjà évalué en un moment auquel le signal maximal du capteur pour la concentration en analyte concernée n'a pas encore été obtenu.
