M.S. / Environmental Science / A continuous real-time in-situ ammonia monitor has been developed. It utilizes the reaction between ammonia gas and sulfuric acid aerosol to form ammonium sulfate for ammonia measurement. A sensitivity-improved Flame Photometric Detector (FPD) is used with the instrument. The detection limit of the monitor for measuring ammonia is 0.4 ppb NH3 with a time resolution of five minutes. The detection limit of the FPD for measuring sulfur has been improved by a factor greater than ten. The present detection limit of the FPD is 0.07 ppb S, which is an improvement over the previous detection limit of 1 ppb S.
