Small amounts of NO2 and O3 in air are determined by utilizing the reactions of these gases with solid alkali metal halides to produce halogen, and the reaction of NO2 with various salts such as PbI2 to produce NO; halogens produced from the reaction may be measured by the use of an electrolytic cell, the output of which is dependent on the halogen concentration of the gas contacting one electrode thereof, while the NO concentration may be determined by the chemiluminescence technique.

A method for the determination of NO2 in air which comprises reacting air containing NO2 with solid PbI2, CuI, BiI3, AuI, PdI2, TlI or ZnI2 to effect an essentially quantitative conversion of said NO2 to NO, and subsequently determining the quantity of NO produced.
