Abstract Nitrogen stable isotope ratio (δ15N) analysis of ammonia gas (NH3) by using a passive sampler is expected to be useful for determining sources of NH3 and for examining environmental dynamics. However, the use of passive samplers for determining the δ15N values of NH3 obtained has not been well validated in laboratory. Here, we evaluated the reliability of the passive sampler under various simulated environmental conditions in the chamber. When the amount of NH3 collected by the sampler was
