Abstract

Fourier transform infrared spectroscopy is an efficient technique for the detection and quantification of molecules in gas mixtures. Measurement results from a mobile laboratory for ambient air analysis and for remote sensing of plume emission with the commercially available K300 spectrometer are reported. CO, CO(2), NO, NO(2), N(2)O, NH(3), CH(4), SO(2), H(2)O, HCl, and HCHO concentrations have been determined with good agreement with in situ results. The on-line multicomponent analysis software is based on line-by-line retrieval and least-squares fitting procedures, including the effects of multiple aerosol scattering and cloud and rain influences.

摘要

傅里叶变换红外光谱法是一种用于检测和定量气体混合物中分子的有效技术。本文报道了使用商用K300光谱仪在移动实验室中对环境空气进行分析以及对羽流排放进行遥感测量的结果。已测定了一氧化碳、二氧化碳、一氧化氮、二氧化氮、一氧化二氮、氨气、甲烷、二氧化硫、水、氯化氢和甲醛的浓度，测量结果与现场测量结果吻合良好。在线多组分分析软件基于逐线反演和最小二乘法拟合程序，考虑了多次气溶胶散射以及云和雨的影响。
