Relative Merits of Gas Chromatography, Colorimetry, and Spectrometry for Air Pollution Studies


Five instruments useful in air pollution studies have been compared. The two recording colorimeters for oxidant and nitrogen oxides have longer response times than the two spectrometric instruments. The gas Chromatograph is specific for many components, however, it requires a preliminary concentration of the sample. All of the instruments are expensive and some, such as the long-path infrared and gas Chromatograph, require personnel with special training. Nevertheless, these units have proved extremely valuable in understanding the complex chemistry of photochemical smog.
