In this paper, an innovative measurement system for odor classification, based on quartz crystal microbalances (QCMs), is presented. The application proposed in this paper is the detection of typical wine aroma compounds in mixtures containing ethanol. In QCM sensors, the sensitive layer is, e.g., a polymeric layer deposited on a quartz surface. Chemical(More)
The response of metal oxide chemical sensors is highly sensitive to operating temperature, and it is well known that this temperature has to be controlled within few degrees. Moreover operating sensors with variable temperature allows enhancing chemical sensing system capabilities. In this paper a simple but highly flexible temperature control system for(More)
In this paper the authors propose a new and simple Nafion<sup>reg</sup> based amperometric sensor and a dedicated measurement system and measurement protocol. The system has a linear response to NO<sub>2</sub> concentration and a sensitivity up to 90 nA/ppm. Moreover, the developed sensor shows a satisfactory repeatability and a low cross-sensitivity to(More)
