Abstract

A new system of quantitative analytical spectroscopy using a continuously scanning tunable dye laser is proposed. This system can detect simultaneously many components of pollutant gases by one scan. The maximum number of detectable gases and the sensitivity of the detection is analyzed. The absorption spectrum is calibrated to the output of the laser, to the standard spectrum (Na), and the interpolating Fabry-Perot interferometer. The gas concentration is calculated by the method of least squares. A fundamental experiment by using a rhodamine 6G dye laser is done. Three kinds of gases, NO2, 12 and Br2, are separately analyzed quantitatively.
