The Reston Stable Isotope Laboratory (RSIL) produces for USGS and other national and international public and private organizations.

The Reston Stable Isotope Laboratory (RSIL) provides the following:

  • hydrogen, carbon, nitrogen, oxygen, and sulfur forensic-quality, stable isotope-ratio analyses of water, rock, and biological samples for environmental studies 
  • noble gas analyses of water for groundwater and surface-water studies 
  • tritium analyses of water for groundwater dating 
  • hydrogen-, carbon-, nitrogen-, oxygen-, and sulfur-bearing isotopic reference materials for calibration of mass spectrometers and laser absorption spectrometers 

Our customers include the U.S. Geological Survey, other Bureaus of the Department of the Interior, other federal agencies, state agencies, county agencies, private organizations, and organizations outside the United States.

 

 

    • Reference Materials and Calibration Services

      The Reston Stable Isotope Laboratory (RSIL) of the United States Geological Survey provides isotopic reference materials and calibrates user-supplied materials. Reference materials are suitable for use in calibration of analytical instrumentation, for testing analytical methodologies, and for use as quality control samples.
