Abstract
Abstract An odor identifying apparatus comprising a gas sensor unit including at least two sensors having different characteristics for simultaneously detecting odorous components arising from a sample and outputting detection signals, a display device for displaying detection results from the sensor unit as a single output signal, and an ozone gas generator for supplying ozone gas into a chamber in which the sample is placed. An odor identifying method is also disclosed which identifies odorous components by using this apparatus.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
77 words
An odor identifying apparatus comprising: a gas sensor unit including at least two sensors having different characteristics for simultaneously detecting odorous components arising from a sample and outputting detection signals; and display means for displaying detection results from said sensor unit as a single composite output signal representing a ratio between outputs from said respective gas sensors. wherein an ozone gas generator is provided for supplying ozone gas into a chamber in which said sample is placed.
Claim 2
Dependent Claim
77 words
An odor identifying apparatus comprising: a gas sensor unit including at least two sensors having different characteristics for simultaneously detecting odorous components arising from a sample and outputting detection signals; and display means for displaying detection results from said sensor unit as a single composite output signal representing a ratio between outputs from said respective gas sensors. wherein an ozone gas generator is provided for supplying ozone gas into a chamber in which said sample is placed.
Claim 3
Dependent Claim
23 words
An odor identifying apparatus as claimed in claim 1, further comprising a clean gas injector for supplying a clean gas into said chamber.
Claim 4
Dependent Claim
24 words
An odor identifying apparatus as claimed in claim 1, further comprising a sample holder for supporting said sample, said sample holder including heating means.
Claim 5
Dependent Claim
17 words
An odor identifying apparatus as claimed in claim 1, wherein said display means is an X-Y recorder.
Claim 6
Dependent Claim
21 words
An odor identifying apparatus as claimed in claim 4, wherein said X-Y recorder gives a display by incorporating a time factor.
Claim 7
Dependent Claim
93 words
An odor identifying method comprising the steps of: placing a sample on a sample holder; simultaneously detecting odorous components arising from said sample with at least two gas sensors included in a gas sensor unit and having different characteristics, and outputting detection results; and displaying said output signals at display means as a single composite output signal representing a ratio between outputs from said respective gas sensors, wherein, prior to detecting said odorous components, ozone gas generated by an ozone gas generator is supplied into a chamber in which said sample is placed.
Claim 8
Dependent Claim
93 words
An odor identifying method comprising the steps of: placing a sample on a sample holder; simultaneously detecting odorous components arising from said sample with at least two gas sensors included in a gas sensor unit and having different characteristics, and outputting detection results; and displaying said output signals at display means as a single composite output signal representing a ratio between outputs from said respective gas sensors, wherein, prior to detecting said odorous components, ozone gas generated by an ozone gas generator is supplied into a chamber in which said sample is placed.
Claim 9
Dependent Claim
31 words
An odor identifying method as claimed in claim 6, wherein said odorous components are detected by said gas sensors while heating said sample with heating means included in said sample holder.
Claim 10
Dependent Claim
33 words
An odor identifying method as claimed in claim 6, wherein a clean gas is supplied by a clean gas injector into said chamber after ozone gas is generated by said ozone gas generator.
Claim 11
Dependent Claim
17 words
An odor identifying method as claimed in claim 6, wherein said display means is an X-Y recorder.
Claim 12
Dependent Claim
21 words
An odor identifying method as claimed in claim 9, wherein said X-Y recorder gives a display be incorporating a time factor.
Claim 13
Dependent Claim
24 words
An odor identifying apparatus as claimed in claim 2, further comprising a sample holder for supporting said sample, said sample holder including heating means.
Claim 14
Dependent Claim
17 words
An odor identifying apparatus as claimed in claim 2, wherein said display means is an X-Y recorder.
Claim 15
Dependent Claim
33 words
An odor identifying method as claimed in claim 7, wherein a clean gas is supplied by a clean gas injector into said chamber after ozone gas is generated by said ozone gas generator.
Claim 16
Dependent Claim
17 words
An odor identifying method as claimed in claim 7, wherein said display means is an X-Y recorder.
