Paper Abstract

We previously reported the use of hollow metal and dielectric lined waveguides as gas cells used in real-time Raman spectroscopy of gas mixtures. Our team has constructed a multi-gas Raman sensor system capable of measuring molecular components in most gas mixtures with sub-percent accuracy and a sub-second sampling rate. This combination of speed and accuracy is enabled by the novel combination of optimized sample-cell collection and appropriate gas-stream configuration. Here, we discuss the new state-of-the-art in Raman process-gas analysis and share relevant testing data on our optimized system for potential industrial end-users. We conclude that a paradigm shift in technology for gas measurement applications could result from the instrumentation developed herein.
