Application in photo acoustic spectroscopy


Photo Acoustic Spectroscopy (PAS) is an analytical instrument with a mechanism similar to that of a secondary quantum optical spectrometer.

Photo Acoustic Spectroscopy (PAS) is an analytical instrument with a mechanism similar to that of a secondary quantum optical spectrometer. PAS is to change the wavelength of light irradiation sample, the acoustic sensor to collect the sound of the sample, record and analyze the light wavelength corresponding to the volume of the spectrum. In principle, PAS is a spectroscopic method that captures the thermal energy generated by the substance after it absorbs light in the form of sound.
