Abstract
Owing to recent rapid progress in laser light sources and detectors, applications of Raman spectroscopy have been expanding to various fields such as industries, foods, environmental measurements and medicine. In this review, we discuss the potential of Raman spectroscopy in highly sensitive gas analysis. Examples of the analysis of metabolic gases by Raman spectroscopy will be described in connection with the possibility of respiratory gas analysis by Raman spectroscopy. In addition, compact Raman system for gas analysis designed by our group will be presented.
