Abstract
Fourier transform spectroscopy substantially reduces the limitations on infrared methods of pollution measurement. EPA has used long path cells and Fourier transform spectrometers for pollutant measurement both in the laboratory and in the field. Labile pollutants are best measured in the open air using folded paths of one kilometer or more. Stable pollutants are best measured in miniature folded-path cells after concentration and separation from the main gases in the air. Examples of ambient air pollution measurement are given.
