Paper Abstract

This paper describes a long path Fourier transform infrared spectroscopy system which is used to analyze ambient gas. Some VOCs (C2H2, C2H4) are measured with this system in laboratory. As different VOCs has unique infrared absorbing spectrum, we retrieve VOCs concentration based on the nonlinear least square algorithm. The result shows that the system is stable and rapid. The retrieved concentrations are very close to real value. The system can used to monitor and research VOCs in ambient gas.
