Stable Isotope Facility

The stable isotope facility of the University of Arizona – Biosphere 2 conducts stable isotope analysis of water and air samples in support of the research conducted at the Landscape Evolution Observatory (LEO) and the Rainforest biome. Located centrally in the LEO bays, the facility houses state-of-the-art laser absorption spectroscopy instrumentation for stable isotope ratio analysis of hydrogen and oxygen in liquid water and water vapor as well as of carbon and oxygen in carbon dioxide. The instrumentation is used in conjunction with a dense network of sample inlets in atmosphere, subsurface, and discharge conduits to facilitate acquisition of detailed data in space and time.
