| 摘要 |
<p>The invention relates to a sensor device (10) for selectively detecting low concentrations of functional hydrocarbons in the gas phase using at least one resistive sensor (11) that can be heated, wherein the sensor device comprises at least one surface ionization sensor (11, 20) that can be heated and that is located in an electric field. Said sensor device is structurally simple and can detect small concentrations of toxic hydrocarbons, for example dimethylaniline, dibutylamine or drugs on the basis of amphetamine, in the atmosphere.</p> |
