A biological gas detection apparatus of an embodiment of the present invention includes: 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 gas sensors output when detecting the biological gas and the database.

Biological gas detection apparatus and biological gas detection method

The present invention provides a gas detection method and detection apparatus that provide better sensitivity and faster recovery after response than conventional gas detection methods and apparatus, by improving on these conventional methods and apparatus. The present invention is a gas detection method, in which the target gas is detected while oxygen is supplied to a sensor elementof a metal oxide-type gas sensor, wherein the target gas is detected while water vapor is supplied to the sensor element, and is also a gas detection apparatus equipped with an oxygen supply meansfor supplying oxygen to a sensor elementof a metal oxide-type gas sensor, said gas detection apparatus being provided with a water vapor supply meansfor supplying water vapor to the sensor element

Gas detection method and gas detection apparatus

A gas chromatograph having the capability of performing a reliable measurement under a condition that the baseline of a detector output is stabilized, and a breath component analyzer using the same are provided. This gas chromatograph comprises a gas separation column accommodating a member for causing a flow delay depending on gas component; air pump for supplying an air as a carrier gas into the gas separation column; gas supply port formed in a gas flow channel extending between the air pump and the gas separation column, and adapted to supply a subject gas containing a target gas component to be detected into the carrier gas flowing in the gas flow channel; buffer tank provided upstream of the gas supply port; and a detector for detecting the gas component of the subject gas supplied into the gas separation column.
