| Abstract |
Tungstic acid surfaces chemisorb NH3 and HNO3. Collection of these gases is possible by sampling with a hollow tube the interior of which is coated with tungstic acid. Thermal desorption followed by a simple separation and detection by a chemiluminescent NOx analyzer permits analyses at the ppb and lower concentration range for gaseous and particulate forms of the analytes. |
