Ppb-level detection of methane based on an optimized T-type photoacoustic cell and a NIR diode laser
This paper presents an optimized T-type resonant photoacoustic (PA) cell for methane (CH(4)) gas detection. The noise transmission coefficients and PA field distributions of the T-type resonant PA cell have been evaluated using the finite element method and thermoviscous acoustic theory. The optimiz...
