Popis: An instrument for measuring atmospheric ozone concentrations has been developed that uses chemiluminescent dyes in various solvents. Solutions of rosin Y in ethylene glycol were effective for measuring ambient ozone at a response frequency of 7 Hz and a detection limit of 0.2 ppb ozone. Other atmospheric species, including humidity, gave no interference. The response to ozone is linear over the range of 0.2-400 ppb ozone. A successful comparison of the chemiluminescent instrument to a commercial ozone analyzer was made during measurement of ambient ozone concentrations in Denver air. 11 references, 3 figures, 3 tables.
