Paper Abstract

The design and performance of laser and flash lamp fluorescence NO2 monitors are compared with respect to sensitivity, size, specificity, reliability and economy. A detectability of ppb for a one minute integration time in ambient air was achieved for both units. The sensitivity of the laser prototype can be increased to achieve 0.1 ppb detectability. A variety of tests, including use of smog chambers, has shown that our NO2 fluorescence monitors are free of interferences; namely, they are specific for NO2. Results obtained in monitoring ambient NO2 levels at our location (El Segundo, California) with the prototype instruments are presented and discussed.
