We approached the problem of sensing gaseous pollutants and malodors originated as a result of decomposition of organic compounds via chemoresistive sensors. A set of four sensors based on screen-printed films of mixed tin and titanium oxides, mixed tungsten and tin oxides, and zinc oxide has been tested vs. the main gaseous components of these malodors. N-butanol was also considered because of its importance as a reference gas in the odorimetric intensity scale. We found that, under proper working conditions, the films can sensitively detect such gases either in dry or in wet environments, within the range of concentrations of interest for monitoring.

Abstract

We approached the problem of sensing gaseous pollutants and malodors originated as a result of decomposition of organic compounds via chemoresistive sensors. A set of four sensors based on screen-printed films of mixed tin and titanium oxides, mixed tungsten and tin oxides, and zinc oxide has been tested vs. the main gaseous components of these malodors. N-butanol was also considered because of its importance as a reference gas in the odorimetric intensity scale. We found that, under proper working conditions, the films can sensitively detect such gases either in dry or in wet environments, within the range of concentrations of interest for monitoring.
