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

用于测定氨气中氮稳定同位素比的被动采样器的实验室验证

摘要 使用被动采样器对氨气 (NH3) 进行的氮稳定同位素比 (δ15N) 分析有望用于确定 NH3 的来源和检查环境动态。然而，使用被动采样器来确定所获得的 NH3 的 δ15N 值尚未在实验室得到很好的验证。在这里，我们评估了无源采样器在室内各种模拟环境条件下的可靠性。当采样器采集的 NH3 量为
