METHOD AND DEVICE FOR DETECTING FUMIGANTS IN AIR SAMPLES

摘要

The invention relates to a method and to a device for detecting fumigants in air samples. The devices can for example be configured as a portable analyze r (10) that has a sound (11) for taking air samples from the soil. Detection means (16) generate electrical signals upon contact with the air sample, sai d signals being generated in accordance with the concentration of the fumigant s to be detected in the air sample. The detection means (16) according to the invention comprise a mass-sensitive sensor, for example an array of quartz microbalances with suitable selective surface layers.
