Abstract Currently used instruments for the measurement of O3, SO2, and the oxides of nitrogen are briefly described. The first utilizes the chemiluminescence of the gas phase reaction of O3 with ethylene, the second uses the chemiluminescence of excited diatomic sulfur formed in the cool hydrogen flame by reaction between SO2 and H atoms, while the third depends upon the chemiluminescent reaction NO+O3. Nitrogen dioxide is thermally dissociated into NO and measured as such. Newer instruments, now under development, that are described include (1) a photofragment detector for NO2, operating on photolytic cleavage to yield O atoms, which are then measured via the luminescence of their reaction with an excess of added NO, and (2) the UV fluorescence instrument of Okabe.
