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 analyzer10equipped with a stab probe11for sampling soil air. There are provided detection means16which, 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 means16comprise at least one mass-sensitive sensor, for example an array of quartz microbalances, which have suitable selective surface layers.
