Discrimination of odorous materials by the quartz resonator sensors with synthetic lipid membranes was investigated. Using five sensors with various membranes. we measure responses to five odorous materials which were included in the T&T olfactmeter for testing a human olfactory sense. Discrimination from the patterns of the sensors response were difficult. because the patterns were similar. We apply a principall component analysis to the sensor responses. The result was largely influenced by the concentrations of the odorous materials. With a discriminant analysis, the five odorous materials were found to be well discriminanted, even though the concentrations were different. We also found that the time constants of the sensor responses were also good parameters for discrination and it enables to shorten the time for measurement.
