The Stable Isotopes for Biosphere Science (SIBS) lab

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 approaches. Carbon (δ¹³C), nitrogen (δ¹⁵N), hydrogen (δ²H) and oxygen (δ¹⁸O) isotope ratio analyses are routinely conducted in the laboratory.
