철도차량 내장재의 연소가스 정량분석에서의 PLS 기법 적용 연구

초록

This study was to quantify the 5 toxic components(CO, CO2, NO, SO2, HCN) of railway car's interior materials using FT-IR instrument. For this purpose, the concentration of toxic component gases was obtained IR spectra and measured by gas analyzer for comparison purpose. And Partial Least Squares method was applied. The experiment was followed by the BS.6853 Annex B.1(NF X 70-100) standard which is based on the specimen mass. During combustion, Water vapor and Carbon dioxide gases are mainly generated. Particularly, the water vapor is interfered with the target component of SO2, NO. To solve this problem, Some of the IR spectra was used to constitute PLS method and remaining spectra was predicted its concentration using the Partial Least Squares method.
