Nu Instruments | High Throughput Isotope Ratio Measurements of Uranium Particles for Nuclear Forensics Using Laser Ablation and Time-of-Flight ICP-MS
This application note demonstrates how the Nu Vitesse TOF-ICP-MS, combined with a fast washout laser ablation system, enables rapid isotope ratio measurements of individual uranium particles. By collecting the full mass spectrum simultaneously and at high speed, Vitesse can analyse thousands of particles in a single session while maintaining the isotope ratio information needed for forensic investigations.
Nuclear forensic investigations often require the analysis of large numbers of individual uranium particles to identify material origins, production processes, and isotopic variations. Traditional bulk measurements can mask important particle-to-particle differences, making single-particle analysis an increasingly valuable approach.
The study shows how high-throughput laser ablation TOF-ICP-MS can identify particles with different isotopic compositions within the same sample, providing a more complete understanding of complex materials than bulk analysis alone.
Key Takeaways:
- High-throughput uranium particle analysis using laser ablation TOF-ICP-MS
- Simultaneous measurement of uranium isotopes from individual particles
- Rapid screening of thousands of particles in a single analysis
- Identification of isotopically distinct particle populations
- Improved sample characterisation for nuclear forensic applications
