Description
Technical Field
The utility model belongs to the technical field of the optoacoustic spectrum detects technique and specifically relates to a gas humidification device for optoacoustic spectrum detects is related to.
Background
In conventional spectroscopy, light scattering, reflection, is the largest disturbance because the amount of light energy absorbed by a sample is determined by measuring the intensity of the transmitted light and subtracting the intensity of the transmitted light from the incident light intensity, and the light-tissue interaction process is necessarily accompanied by some reflection, scattering, and other light losses, which result in a reduction in the incident light intensity. In addition, conventional spectroscopy detects the transmitted light signal after the interaction of light with tissue, and therefore the sample must have a certain light transmission. In contrast, photoacoustic spectroscopy detects mechanical waves generated by tissue absorbing light energy, and the intensity of the mechanical waves directly reflects the amount of light energy absorbed by a substance. Thereby avoiding signal interference caused by reflection, scattering and the like of light in the sample; meanwhile, the irradiation power of incident light can be properly increased aiming at a weakly-absorbed sample to improve the signal-to-noise ratio. Therefore, the method is widely applied to detection of various samples, such as transparent or opaque solid, liquid, gas, powder, colloid, crystal or amorphous, and the like, and essentially solves the problems of detection of samples with weak absorption, strong scattering, opacity and the like by the traditional spectroscopy.
In the photoacoustic spectroscopy oil-gas detection technology, gas separated from transformer oil enters detection equipment (photoacoustic cell) through a gas pipeline. Experiments prove that if the gas has certain water molecules, namely certain humidity is kept, the detection of the photoacoustic spectrum is facilitated.
Therefore, there is a need for a gas humidification apparatus for photoacoustic spectroscopy detection to facilitate photoacoustic spectroscopy detection of gases.
