Abstract
The present invention provides an odor measuring apparatus capable of assuredly detecting and evaluating such odors that cannot be detected by a measurement apparatus using conventional odor sensors. In an embodiment of the present invention, a gas sample to be measured is introduced into the columnof a gas chromatographto temporally separate it into odor components, which are then introduced into a mass spectrometer (MS)and an odor discriminatorin parallel. The data processorcreates a chromatogram and/or a mass spectrum from the detection signals generated by the detectorof the MS, and also calculates the similarity of each odor component to standard odors and/or the degree of contribution from the detection signals generated by the detection circuitof the odor discriminator. The processordisplays a similarity radar chart or similar graphic information on the display, where each peak present on the chromatogram is associated with the information. Even if the odor to be measured is a mixed odor, the GCtemporally separates it into sample components, and each sample component can be assuredly and objectively detected by the odor discriminator
