The Picarro G5102-i isotopic and gas concentration analyzer enables measurements of site specific and bulk δ¹⁵N in N₂O. It is an ideal solution for discerning and measuring the source of N₂O emissions real-time in the field or through grab-sample measurements in the lab. The isotopomers of N₂O can be used to probe sources and sinks in the global nitrogen cycle by identifying nitrification and denitrification processes in soils and water.
