Nitrogen dioxide detection using a coulometric method.

The adaptability of the Mast Model 724 Series Meter for the monitoring of nitrogen dioxide is discussed. Sensitivity curves for the instrument are presented. The range of applicability (the range of concentrations which are accurately measurable with the device) are defined. The interrelationship of ozone and nitrogen dioxide as detected by the instrument is discussed. The interference effect of sulfur dioxide in measuring NO/sub 2/ is discussed. 6 references, 9 figures.
