IRMS

Stable Isotopes Mass Spectrometer

The STRI Soils Laboratory in Panama operates an Isotope Ratio Mass Spectrometer (IRMS) for the determination of stable isotopes of carbon, hydrogen, oxygen and nitrogen in environmental samples. A variety of samples can be analyzed, including soils, plant and animal tissue, geological samples, gases, and waters. We also operate a cavity ring-down spectrometer for high precision determination of δ18O and δ2H in liquids.
