Claim Text:
1. A biological gas detection apparatus comprising: a sensor unit including plural types of gas sensors; a control unit of the sensor unit; a data recording unit; and a data analyzing unit, wherein the data recording unit includes a database on properties of sensitivities of the gas sensors for a single body of a desired gas component, a single body of an interference gas component, and a mixed gas of these that are included in the biological gas, and the data analyzing unit calculates concentration of the desired gas component based on sensitivities of the as sensors which are output when performing detection of the biological gas and the properties of sensitivities of the gas sensors included in the database, and if a sum of sensitivity of the gas sensors is greater than a predetermined first threshold, the biological gas detection apparatus determines that the concentration of the desired gas component is very low as though the desired gas component can be regarded as being absent, or that there is a problem during measurement.
