Abstract

Abstract: Acoustic detectors constitute a key factor of photoacoustic spectroscopy configuration, which is an ultrasensitive gas sensing method. This review aimed to discuss the recent development of acoustic detectors, including capacitive microphone, quartz tuning forks, and optical microphone. An overview of their applications for sensitive, selective, and quantitative trace gas detection was reported, and advantages and limitations of these detectors were presented.
