This document specifies a method for the sampling and analysis of NH3 in ambient air using diffusive sampling. It can be used for NH3 measurements at ambient levels, but the concentration range and exposure time are sampler dependent, and the end user is therefore advised to match the sampler type to the measurement requirement and to follow the operating instructions provided by the manufacturer
