Photoacoustic Spectroscopy Manufacturers

Photoacoustic Spectroscopy is a sensitive technique for measuring small absorptions that is mainly applied when minute concentrations of molecular species have to be detected in the presence of other components at higher pressure. It has become a powerful technique to study concentrations of gases at the part per billion or even part per trillion levels. It is based on the photoacoustic effect. The absorbed energy from the sunlight is transformed into kinetic energy of the sample by energy exchange processes.
