  • Method and device for detecting volatile analytes in air samples
    Patent number: 7950270
    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.

  • Method and device for detecting fumigants in air samples
    Patent number: 7459483
    Abstract: The present invention relates to a method and a device for detecting fumigants in air samples. The device can be designed for example as a portable analyzer 10 equipped with a stab probe 11 for sampling soil air. There are provided detection means 16 which, upon contact with the air sample, generate electrical signals which depend on the concentration of the fumigants to be detected in the air sample. In accordance with the invention, the detection means 16 comprise at least one mass-sensitive sensor, for example an array of quartz microbalances, which have suitable selective surface layers.
