Abstract :
This paper presents the conception and the development of portable gas sensor prototypes for nitroaromatic compounds detection. It is based on quartz crystal microbalance (QCM) principle and a data processing. The sensitive material is a polymer which was chosen for its good sensibility and robustness. This prototype is able to detect 3 ppm of nitroaromatic compound with a high selectivity.
