Open-Path FTIR Monitoring Technology in Environmental Applications

Speaker: Dr. Chia-Yu (Iris) Yang, Postdoctoral Research Associate, Sonny Astani Department of Civil and Environmental Engineering, University of Southern CaliforniaAbstract:Fourier Transform Infrared (FTIR) is a powerful real-time monitoring technique for both detection and quantification of multiple compounds simultaneously even in harsh industrial environments. Several ASTM and EPA measurement protocols using FTIR in industrial or regulatory monitoring have been published in US or in Taiwan.FTIR systems can operate with telescopes transmitting and receiving the IR beam so monitoring of long outdoor paths becomes possible. Such telescope systems are so called "open-path" instruments. Typical environmental applications of open-path monitoring include urban air monitoring in metropolitan areas and fence-line monitoring of industrial sites, other examples such as accidental release detection/identification, and homeland security applications are also seen often. Several cases using open-path FTIR monitoring technology in environmental applications in US and Taiwan will be discussed.
