(GASL) have constructed a prototype of a novel photolytic NO2_x000D_
converter that can be used to upgrade existing NO/NOx chemiluminescence ambient air monitors. These_x000D_
instruments are used by environmental monitoring agencies and emission stack monitors to quantify NO and_x000D_
NO2. Current versions use a non-specific hot metal catalyst to convert NO2 to NO, which is detected by_x000D_
chemiluminescence. GASL's goal is to develop a converter that is specific to NO2. They are seeking to develop_x000D_
a scientific understanding of what gases and gas mixtures cause interferences in the prototype converter to help_x000D_
bring it to market._x000D_
Dr. Osthoff's group will quantify the conversion efficiency in the prototype of a variety of gases in gas streams_x000D_
of known composition, including NO2 (desired) and potentially interfering gases such as HONO, ClNO2,_x000D_
PAN, N2O5, HO2NO2, and HNO3. Interference that might arise from photochemical decomposition of_x000D_
carbonyls and subsequent oxidation of NO to NO2 will be characterized. The experimental results will be_x000D_
rationalized using photochemical box model simulations._x000D_
Alternative quartz photolysis cells (e.g., with smaller inner dimensions) will be constructed and evaluated. The_x000D_
ultimate goal is to allow GASL to deliver a well-characterized, mature, and superior product to market., program purpose french : Scientists at Global Analyzer Systems Ltd. (GASL) have constructed a prototype of a novel photolytic NO2_x000D_
