Abstract An apparatus and a method are described to test the sensing capacities, in the context of an electronic nose, of conductimetric sensors for organic vapours. Such a sensor was constructed using iodine doped poly(2,5-thienylene vinylene) (PTV) and tested in detecting nine ‘representative’ vapours. Responses after 1 min exposure are high and mostly linear with respect to concentrations. Recoveries, however, using 4 min of clean air, are only partial. Yet, responses and recoveries are… CONTINUE READING
