Abstract

The infrared gas analysis device includes: a measurement cell to allow a sample gas containing a component to be measured to flow therethrough; a comparison cell including a reference gas; a pair of light sources provided in one end side of the measurement cell and the comparison cell, the cells being irradiated with an infrared ray from one and the other of the light sources, respectively; and a detection unit provided in another end side of the measurement cell and the comparison cell to detect the component to be measured by using infrared rays output from the measurement cell and the comparison cell. A gas for detection made of a component different from the component to be measured and having an infrared absorption band at at least a part of wavenumbers in infrared absorption bands of the component to be measured is encapsulated in the detection unit.
