| Abstract: | The algorithm for quantitative analysis of passive Fourier-transform infrared spectum (FTIR) of a chemical vapor is given. It can be applied to both real-time processing for chemical vapor and quantitative measurements of chemical vapor column density. The algorithm simultaneously achieves quantitation of the vapor spectral transmission, background removal, real-time calibration for FTIR. Finally, we discuss in detail an example of the use of the algorithm to a simulant DMMP. |
