The Stable Isotopes for Biosphere Science (SIBS) lab at Texas A&M University conducts stable isotopic analysis of organic and inorganic materials. These include plant tissues across spatial and temporal gradients, animal tissues with different origins or from different species, soils recording carbon and nitrogen cycle processes, water from throughout the hydrologic cycle, and atmospheric gases that participate in many biosphere processes.
The lab focuses on research efforts led by the laboratory’s associated scientists, but also provides analyses of outside samples. Samples are analyzed using Isotope Ratio Mass Spectrometry and Laser Spectroscopy approaches. Carbon (δ13C), nitrogen (δ15N), sulfur (δ34S), hydrogen (δ2H) and oxygen (δ18O) isotope ratio analyses are routinely conducted in the laboratory.
