Abstract in another language

The detection of low-level NOx concentrations and the dose of NOx for air-quality monitoring (AQM) is still a huge task and a widely discussed topic. Dosimeter-type NOx sensors detect directly the NOx dose and are advantageous considering mean value detection, linearity of sensor responses, and drift phenomena. The electrical properties of a NOx storage film, here potassium permanganate impregnated on alumina powder, depend linearly on the amount of sorbed NOx. The electrical resistance correlates very well with the amount of formed nitrate and nitrite species. The influence of the deposition method of the sensitive NOx storage material on the characteristic behavior of the dosimeter-type sensors is investigated. Aerosol-deposited dense films (ADM films) behave like porous thick-films, but typical sensor characteristics like detection limits and relative resistance changes seem to be different.
