With the help of rapid scanning Fourier transform infrared FT-IR spectroscopy, 11 IR-activegas products were resolved during the flash pyrolysis process.
This calibration method is of significance to the further analysis of atmospheric transmission and the retrieval of the concentration of infrared activegas in atmosphere.
