摘要
In this paper results concerning the classification of water solutions with ethanol and other volatile organic compounds by means of SnO2 sensors are presented. This study aims at the selection of the most appropriate measurement technique for this application, in terms of both selectivity and repeatability. The final aim of this research is the application of electronic noses based on metal oxide sensors to wine classification. In particular, a comparison is performed between two measurement techniques: chemical transient analysis and sensor temperature modulation. (C) 2002 Elsevier Science B.V. All rights reserved.
