Optimization of microresonator parameters for a quartz-enhanced photoacoustic spectroscopy sensor

Abstract

A Quartz-Enhanced Photoacoustic Spectroscopy based gas sensor was optimized to improve its compact spectrophone design and performance. The impact of a 2-tube microresonator geometry on the detected signal and signal to noise ratio (SNR) was investigated. Experimental studies demonstrate that the l=4.4mm long tubes (ID=0.5mm) result in a significantly… (More)
