Paper Abstract
In the photoacoustic spectroscopy detection system, photoacoustic (PA) cell is the most important component of the system. The conventional structure of photoacoustic cell is H-shape and this type of photoacoustic cell is complicate to design. The portable resonant photoacoustic cell structure is proposed in this paper. The buffer chamber is integrated with the resonator and the structure is more simple. The portable photoacoustic cell is a tubular structure with concave mirror at both ends and a small convex mirror on the side away from the incident window. Laser can enter the resonator directly without buffer chamber and reflect more in resonator. By simulation made by TracePro software, the luminous flux of longitudinal and cross section is analysed. The simulation results shows that the sensitivity of this photoacoustic cell has increased by 69.7%.
