The Application Of Fourier Transform Infrared Spectrometer To The Smoke Determination

The smoke of anti-infrared smoke agent in a self-made miniature smoke chamber was determined by using Forier transform infrared spectrometer. The smoke changing and settling regulation with time were obtained by measuring the IR spectra of smoke at different time dynamically. Through testing the smoke of different quantity of the same smoke agent, it was found that the relationship between the concentration of the main smoke products and the absorbance obeyed Lambert-Beer's Law. Finally, the relationship between the smoke screening ability and reactant agent amounts was obtained by calculating the screening ability of different amounts of reactant agent in three "atmosphere windows".
