CHARACTERIZATION OF TRACE AMOUNTS OP ODORANT S DISCHARGED FROM SEVERAL ODOR SOURCES FOR THE EXPLANATION OF THE RELATIONSHIP BETWEEN SENSORY RESPONSE TO ODORS AND CHEMICAL ANALYSIS DATA

The odorants discharged from several odor sources, i.e., a hospital sick(intensive care unit, ICU)room air, a hospital food, end tidal expired air and others were classified into eight compounds group I, sulfur compounds; group II, lower aliphatic amines; group III, carbonyl compounds; group IV, hydrocarbons; group V, lower aliphatic mono alcohols; group VI, phenols; group VII, lower fatty acids; group VIII, indoles) and were analyzed by a systematic gas chromatography. The graphical representation of these data is effective for rapid recognition of the whole state.A polar co-ordinate pattern display was also proposed for the explanation of the relationship between odor characteristics(odor quality and intensity) and chemical analysis data of the odor charts responsible for each odor discharged from several odor sources.
