Abstract in another language

In times of strict environmental requirements, reliable and low analyte concentration-detecting gas sensing devices are demanded. For that purpose, conductometric gas dosimeters are an interesting alternative to conventional gas sensors. Compared to classical gas sensors, gas dosimeters enable to detect directly the total amount (= the dose) of the analyte by an “irreversible” accumulation of gas molecules, which can be read out electrically. Even the actual analyte concentration can be - additionally -obtained by the derivative of the time-dependent sensor signal. In case of signal saturation, a regeneration has to be initiated, allowing a subsequent measuring cycle. Only few devices working in the accumulating or integrating mode are described in literature, and most of them are field-effect transistors or mass sensitive or optical devices. In this study, conductometric NOx gas dosimeters are directly compared with conventional conductometric sensors.
