Paper Abstract

The spectrophone performance for QEPAS is numerically investigated by using a finite element method. The effect of varying system parameters such as the excitation frequency, relative position between the acoustic resonant tubes and the quartz tuning fork, and the dimensions of resonant tubes are examined A pair of rigid tubes, each with a length of 5.1 mm and an inner diameter of 0.2 mm, positioned 0.6 μm down from the opening and 20 μm away from the edge of tuning fork is suggested for optimal spectrophone performance.
