1. A Fourier transform infrared spectrophotometer to reduce spectral noises due to water vapor, comprising:

  • a sample room in which a sample is placed, a humidifying vessel containing a humidifying agent, which humidifies the inside of the sample room through a first door isolating the vessel and the sample room, and a drying vessel containing a dehumidifying agent, which dehumidifies the inside of the sample room through a second door isolating the vessel and the sample room;

    whereby the first door and the second door are opened or closed to make the difference of IR peak intensity of water vapor smaller than a prescribed value between spectra measured by placing and removing the sample in the sample room.
