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