| Outline of Final Research Achievements |
The Instantaneous Purge (IP) method is the analytical technique developed by G. Imamura for analyzing gaseous samples by chemical sensors; the sensor chip is exposed to a sample gas, followed by purging with air. The purpose of this study is to develop a compact gas measurement system utilizing nanomechanical sensors based on the IP method. In this study, I developed analytical methods and receptor materials for the sensing system. I expanded the scope of the IP method to analyze complicated mixtures of gaseous species, that is odors. Moreover, I developed a new analytical method that realizes gas analysis with an arbitrary gas input pattern. Based on this new method, I succeeded in identification of odors of daily staffs just by wagging a sensor chip over the samples, leading to a more compact and facile sensing system than the one utilizing the IP method.
