This study describes a novel technique for obtaining transient measurements of a chemical species in combustion fields by applying the infrared absorption method. Thus, it is expected that the actual chemical species and fuel vapor concentrations in the flame should be detected in situ inside the combustion engines as well as in gas turbine engines. In general, the absorption spectrum of the chemical species depends on the pressure, concentration, temperature, and optical path length. As a first step, the absorption spectrum of the chemical species (CH_4, CH_2, CO) was measured with calibration cell by means of the FTIR (Fourier Transform Infrared Spectroscopy) method. The temperature ranged from 300K to 800K under constant pressure and constant gas concentration. The temperature dependence of the absorption spectrum was applied to the measurement of the chemical species in a CH_4-Air premixed steady-state burner flame at the atmosphere state. The validity of this measurement method was investigated.
