Welcome to the Colorado Plateau Stable Isotope Laboratory (CPSIL)

Based at Northern Arizona University (NAU), the Colorado Plateau Stable Isotope Laboratory (CPSIL) is designed to serve students, postdoctoral researchers, and faculty at NAU who require carbon, nitrogen, sulfur, oxygen, and hydrogen stable-isotope analyses for their research. Scientists from other institutions are welcome to send us samples for analysis. CPSIL is affiliated with the Colorado Plateau Analytical Laboratory and with the Merriam-Powell Center for Environmental Research.



NOTE: In most cases, we have reduced our prices as of July 1, 2010. We are currently providing fast turnaround on several analyses, including CN and H isotopes on solid samples, and OH isotopes on water samples. Please contact us for details.

To date, CPSIL has analyzed over 350,000 samples.
