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)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Breath analyzer","description":"A breath analyzer includes a light source, a gas cell, a detection unit and a data processing unit.
