Relationship Between Response Patterns of Semiconductor Gas Sensors to Organic Compounds and Their Sensory Properties

Abstract

Headspace gases of 36 compounds having various functional groups were individually injected into a test box where eight semiconductor gas sensors were installed. Relative sensor responses to each compound were correlated to the organicity (the quality or state of being organic) and inorganicity (the quality or state of being inorganic) values of the compound. The sensor responses were classified into six groups by cluster analysis. Compounds belonging to each cluster showed similarity in their organicity and inorganicity.
