Optimization of spectrophone performance for quartz-enhanced photoacoustic spectroscopy

Sensors and Actuators B: Chemical, 2012
We numerically investigate the effects of spectrophone parameters, including the operating acoustic frequency, the relative position of the quartz tuning fork and the excitation laser beam, the gap between the resonant tubes and the tuning fork, and the ...
