ABSTRACT:
The invention relates to a method and a device (16) for detecting volatile analytes in air samples, where a masssensitive 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.
