Abstract

It was studied to analyze the CO2, CO, SO2 standard gases of combustion gases by the open path FT-IR spectrometer with passive mode for remote analysis of air pollutant and volcano gases without IR lamp. As result, it was confirmed to have good linearity with more than 0.9 as correlation coefficients on the calibration curve of CO2, CO concentration by MLR method. But in the case of SO2, because the correlation coefficients were 0.88, the linearity could be lower. Finally, the concentration of three gases was predicted on in-site fire experiment under the condition of quantitative analysis. It could measure high CO2 concentration as predicted result, but didn’t measure the CO and SO2. According to the result, it was possible to measure the combustion gases to long distance by only open path FT-IR spectrometer without infrared lamp
