Quartz enhanced photoacoustic spectroscopy gas package detection device

A quartz enhanced photoacoustic spectroscopy gas package detection device comprises a gas tank (1), a gas pipe valve (3), a window wafer in-put chamber (41), a window wafer (42), a bevel top tube (43) and a window rotation cover (44), an air inlet (51), an air outlet (52), a micro-resonator tube (6), a co-axial coupling packaging unit (7), a quartz tuning fork (8), a quartz tuning fork package member (9), a quartz tuning fork electrode (10), a circuit board fixed bearing (15), an amplifier circuit board (17), a circuit board packaging cover (23) and a gas tank package lid (24). The quartz enhanced photoacoustic spectroscopy gas package detection device ensures that the gap center of two forks of the quartz tuning fork, microresonator center and window center are in a straight line, reduces the optical path adjustment error, increases the detection signal sensitivity, compared with the prior art, fixing is reliable and compact, the miniaturization is achieved, and the sealing property, optimal alignment of the light path and the detection sensitivity are improved.
