摘要：

In this paper, a study is presented aimed at the selection of the most appropriate measurement technique for wine classification. In particular, the problem of detecting typical wine aroma components in mixtures where ethanol is present is taken into account. The literature proposes different solutions in order to enhance metal-oxide sensor selectivity. An interesting approach concerns the application of different measurement techniques. In this work, three methods based on chemical transient, ac measurements, and temperature modulation have been investigated.
