Product Detail

FTIR-Continuous Emission Monitoring System CEMSⅡ/DX-4000


FTIR method: Fourier transform infrared analysis.
The analyzer continuously measures 12 or more gas components using the unique algorism.

  • As a sample gas is measured with the temperature kept high (180°C), high-temperature, high-humidity, and water-soluble gases can be measured.
  • It has an excellent corrosion resistance and uses a simple measurement method that does not need water removal.
  • As a quantitative analysis system is used, a calibration gas is not basically needed.
    Only the zero gas measurement is performed using a nitrogen gas.
  • Gas

Operating Principles

Respective molecules that constitute physical properties have their unique frequency of vibration, and only the infrared rays that correspond to the frequency of vibration are absorbed. Thus, the substance can be identified from the frequency distribution at the absorption peak. Infrared rays regarded as interference light by the interferometer are absorbed by the sample gas in the cell to obtain the frequency intensity specific to each molecule. The spectrum is obtained from the frequency intensity through the Fourier transformation, the mutual interference compensation and absorption band are selected, and then the gas is identified and the concentration is calculated from the library and CLS algorism.
