The miniDOAS: Low Cost, High Performance Contactless Ammonia Measurements

National Institute for Public Health and the Environment;D.P.J. Swart;M. Haaima;A.J.C Berkhout;H. Volten;J.B. Bergwerff
February 1st 2013

Knowledge of atmospheric ammonia concentrations is important, but ammonia is difficult to measure. We report here on the development of a low-cost ammonia measuring differential optical absorption spectroscopy (DOAS) instrument, based on a small sized and low priced spectrograph.
