Gailey, P., W. McClenny, R. Braman, AND T. Shelley. SIMPLE DESIGN FOR AUTOMATION OF TUNGSTEN(VI) OXIDE TECHNIQUE FOR MEASUREMENT OF NH3, AND HNO3. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/J-83/144 (NTIS PB84144278).
Description:
The tungstic acid technique for collection and analysis of NH3 and HNO3 concentrations in the ambient air has been automated in a simple and cost-effective design. The design allows complete separation of HNO3 and NH3 during detection. Unattended operation in field trials has been demonstrated, and a three-day run sequence with hourly updates is shown.
