NEW TECHNIQUES FOR THE MEASUREMENT OF AIR POLLUTANTS
Measurement research in air pollution at the National Bureau of Standards includes that applicable to ambient air, stack emissions, and automotive emissions. The fluorescence monitor for sulfur dioxide developed by Dr. Okabe and his colleagues has been applied commercially to the problem of stack monitoring. This apparatus is described and its capabilities delineated. The technique of laser magnetic resonance for the measurement of NO at concentrations typical of stack emission and auto exhaust has similarly been extended to include ambient concentrations. In addition, progress has been made in the direction of simultaneous measurement of NO2 by the same technique. The most recent data obtained by the laser magnetic resonance technique is presented.
