T&T olfactometer standard odors for measuring olfactory sense seem to be suitable standard odorants for use in comparing sensor response with human perception. The responses of quartz resonator sensors covered with synthetic lipid membrane to five odors supplied with the T&T olfactometer were evaluated. The five odorants were not individually distinguishable from the response patterns, because the sensors had low sensitivity for the five odorants. The five odorants were discriminated after applying principal component analysis to the response data. Comfort or discomfort feelings regarding five odors were successfully distinguished with the responses of three sensors and principal component analysis. New sensors coated with urethane resins were demonstrated and found to be promising candidates for use as sensors with high sensitivity for the T&T olfactometer. © 1997 Scripta Technica, Inc.
