IdealPhotonics' Photoacoustic Spectroscopy is a technique that analyzes the composition and concentration of substances by detecting the acoustic signals generated after a substance absorbs light energy. It combines the high selectivity of optical excitation with the high sensitivity of acoustic detection.By directly detecting the absorption characteristics of substances through the photoacoustic effect, it combines the high selectivity of optical methods with the background interference-free advantages of acoustic detection, making it particularly suitable for trace analysis or detection of complex matrices.
