PROBLEM TO BE SOLVED: To provide an analyser capable of performing an accurate measurement even when lead is not used.SOLUTION: An analyzer includes: a light emitting part 2 for emitting light of an infrared wavelength region; a sample cell 3 in which a measurement sample is stored; a heat removal filter 6 arranged between the light emitting part 2 and the sample cell; a detection filter 4b for transmitting light only of a specific wavelength region; and a detection mechanism 4 for detecting the light transmitting the sample cell and measuring a predetermined component included in the measurement sample using the detected light. The light emitting part includes: a light source 2a for emitting the light of an infrared wavelength region; a body 2b for storing the light source provided with an opening for emitting the light from the light source; and a window part 2c provided so as to close the opening. The heat removal filter transmits the light of the wavelength region used for measurement of the predetermined component, and shuts down the light of the infrared wavelength region different from the infrared wavelength region shut down by the window part. |
