Abstract

Measurements made using two different types of ammonia monitors during a two-month field study in the summer of 1994 are discussed. The first instrument was a diode-laser based open path monitor designed for automated operation in an industrial environment. The second is a point monitor based on thermal decomposition of ammonia to NO and subsequent analysis by O₃ - NO chemiluminescence. The two monitors provided consistent measurements of ammonia during weeks of continuous unattended operation.
