摘要： A breath analyzer includes a light source, a gas cell, a detection unit and a data processing unit. The light source emits infrared light of a wavelength band including an absorption line for acetone. A breath containing sample gas is introduced to the gas cell. The infrared light is incident on the gas cell. The detection unit receives transmitted light emerging from the gas cell, and outputs a sample signal value corresponding to an acetone discharge amount. The data processing unit determines an approximation formula of dependence of fat oxidation rate on acetone discharge amount in advance, and calculates a fat oxidation rate for individual sample signal values using the approximation formula. When the acetone discharge amount (microliter/min) is x, the fat oxidation rate (milligram/min) y is approximated by a following formula: y=Ax+B (where A and B are constants).

摘要： A gas measuring apparatus includes a cell portion, a light source portion, a detection portion, and a control portion. The cell portion includes a space into which a sample gas containing breath containing a first isotope of carbon dioxide and a second isotope of carbon dioxide is introduced. The light source portion changes a wavelength of the light in a band of 4.345 μm or more and 4.384 μm or less. The detection portion performs an operation including first detection of an intensity of the light passing through the space and second detection of an intensity of the light passing through the space into which the sample gas is not introduced. The control portion calculates a ratio of an amount of the second isotope to an amount of the first isotope based on a result of the first detection and a result of the second detection.

摘要： An exhalation diagnostic devise includes a cell portion, a light source, a detector and a controller. The cell portion includes space into which a sample gas containing first and second substances is introduced. The detector detects an intensity of the light transmitted through the space. The controller, at a time of a first operation, causes the light source to change a wavelength, and calculates a ratio of an amount of the second substance to an amount of the first substance. And the controller, at a time of a second operation performed in one respiration, causes the light source to set the wavelength of the light to a third wavelength, determines whether concentration of at least one of the first substance and the second substance exceeds a set value or not, and starts the first operation when the concentration exceeds the set value.
