Technical Principle

Photoacoustic spectroscopy gas detection technology is a gas detection technology based on the photoacoustic effect, which is generated by gas molecules absorbing specific wavelengths of electromagnetic radiation (such as infrared light). If a gas is placed in a closed container, the temperature rise after the gas absorbs radiation will cause the gas pressure to increase. At this time, if pulse light is used to irradiate the gas, a sensitive microphone can detect pressure fluctuations with the same frequency as pulse light.

To apply the photoacoustic effect to practical detection, it is first necessary to determine the specific infrared absorption spectrum of each gas; The second step is to determine the proportional relationship between the intensity of pressure waves generated by gas absorption energy and gas concentration. Therefore, by selecting an appropriate wavelength and combining it with the detection of pressure wave intensity, not only can the presence of a certain gas be verified, but its concentration can also be determined. Even qualitative and quantitative analysis can be performed on certain mixtures or compounds, which is the advantage of applying photoacoustic spectroscopy (PAS) technology.
