具備してなる赤外線分析計。 Infrared rays that alternately irradiate a reference cell filled with a standard gas and a comparison cell supplied with a measurement gas with infrared rays of a specific wavelength, detect the infrared rays absorbed by the reference cell, and analyze the component to be measured in the measurement gas. The analyzer consists of a filter that transmits only a specific wavelength of infrared light emitted from a pulsed light source, a position detector that detects the position of a rotating sector and outputs a sector position detection signal, and a standard gas inside. an enclosed reference cell, a comparison cell filled with a measurement gas, a pyroelectric sensor that receives infrared rays transmitted through the reference cell and measurement cell and outputs a detection signal corresponding to the amount of light; and the position detector. In response to the sector position detection signal from the pyroelectric sensor and the detection signal from the pyroelectric sensor, the amount of pulsed infrared rays transmitted through the reference cell and the amount of pulsed infrared rays transmitted through the comparison cell are separated and subjected to a predetermined calculation. Calculate the gas concentration of the component to be measured contained in the measurement gas and output it as a measurement signal, and also calculate a pulse power control signal from the sector position detection signal and the amount of pulsed infrared light transmitted through the reference cell to turn on the pulse light source. An infrared analyzer comprising a controller that sends out a pulsed power supply.
