OSTI ID:7212150

This method covers the manual determination of nitrogen dioxide (NO/sub 2/) in the atmosphere in the range from 4 to 10,000 ..mu..g/m/sup 3/ (0.002 to 5 ppM) when sampling is conducted in fritted-tip bubblers. For concentrations of NO/sub 2/ in excess of 10 mg/m/sup 3/ (5 ppM), as occur in industrial atmospheres, gas burner stacks, or automotive exhaust, or for samples relatively high in sulfur dioxide content, other methods should be applied. The maximum sampling period is 60 min at a flow rate of 0.4 liter/min. The NO/sub 2/ is absorbed in an azo-dye-forming reagent. A red-violet color is produced within 15 min, the intensity of which is measured spectrophotometrically at 550 nm.
