Abstract

Abstract Until now, the photoacoustic spectrum (PAS) analysis technology can’t face the need for sulfur hexafluoride (SF6) gas-decomposition products due to the high noise level, big shock and low accuracy. In this manuscript, we present a portable SF6 gas-decomposition PAS gas analysis system based on mid-infrared quantum cascade laser (MI-QCL). Because the narrow linewidth, high speed tunable and stability wavelength of MI-QCL, our PAS gas analysis system has a good performance. A platform for MI-QCL PAS system is set up in our work. The accuracy of quantitative detection for sulfur dioxide (SO2), hydrogen sulfide (H2S) and carbon monoxide (CO) in SF6 gas background mixture gas is 0.5ppm, 0.1ppm and 0.1ppm, respectively. Experiment results demonstrate the MI-QCL PAS system not only has a high detection accuracy, but also has a small system volume. This work gives a novel solution method for PAS system miniaturization in the future.
