Transient response curves for exposure to aromas from several kinds of
alcohols are observed using a Japanese-lacquer-film-coated quartz res
onator gas sensor. The shape of the transient response curves strongly
depends on the ethanol concentration of alcohols. The pattern recogni
tion analysis using principal component or neural network analysis is
carried out using four parameters which characterize the shape of the
transient response curve. The recognition probability using neural net
work analysis for aromas from alcohols is 100% for 25 trials.
