LLNL researchers—and visiting scientists—use LLNL’s world-class experimental resources and modeling codes as they explore challenges in nuclear science and radiochemistry.

LLNL’s Nano-Secondary Ion Mass Spectrometer


LLNL has more than 50 radiological labs designed for studying radioactive isotopes. In addition, our technology includes:

  • Accelerator Mass Spectrometry. Conduct ultra-sensitive isotope ratio measurements.
  • Resonance Ionization Mass Spectrometry. Measure isotopes with lasers that ionize atoms.
  • Nano-Secondary Ion Mass Spectrometry. Analyze isotope ratios in sub-micron samples.
  • High-Resolution Mass Spectrometry. Measure isotopic compositions of environmental samples.
  • Nuclear Magnetic Resonance Spectrometry. Analyze radiological and chemical threat agents.
  • Transmission Electron Microscopy. Capture high-resolution images of nanoscale and microscale material processes.

LLNL supports the development of open-access findable, accessible, interoperable, and reusable (FAIR) databases and codes that are critical to predicting the long-term behavior of metals, radionuclides, and major elements in Earth systems. Our code resources include:

  • Thermodynamic modeling. Simulate the solution and solid phase speciation in Earth Systems.
  • Sorption. Develop codes and databases that simulate reactions at the solid-water interface.
