DOAS differential absorption spectroscopy is a spectral analysis method developed on the basis of absorption spectroscopy for accurate quantitative analysis of the concentration of the measured gas. It is a method of accurately identifying different gases and monitoring the concentration of the measured gas by utilizing the distinct "differential absorption structure" of the measured gas in the selected frequency band.
