Invention Reference Number

A novel method enables the enrichment and analysis of paramagnetic actinide particles suspended in complex environmental matrices. The approach enhances the ability to detect and characterize actinide materials used in nuclear processes while preserving particle integrity. By offering improved particle separation and single-particle analysis, the technology supports safeguards, nuclear forensics, and compliance monitoring by regulatory bodies such as the International Atomic Energy Agency.
Description
This invention combines high-gradient magnetic filtration with advanced single-particle mass spectrometry to isolate and characterize actinide-containing particles from heterogeneous mixtures. The filtration device, which uses an optimized arrangement of permanent magnets, passively enriches paramagnetic actinide particles based on their magnetic properties. Unlike conventional separation techniques, the system does not alter the morphology or composition of the particles, enabling accurate, downstream characterization. The captured particles are analyzed with a high-resolution spectrometry platform capable of detecting isotopic composition at the single-particle level. This approach eliminates the need for caustic digestion or sample homogenization and offers a more precise understanding of actinide distribution in complex materials.
Benefits
- Enriches actinide particles without altering their morphology or composition
- Enables high-resolution, single-particle analysis without destructive sample preparation
- Supports safeguards and verification with improved data fidelity
Applications and Industries
- Nuclear proliferation monitoring and compliance
- Environmental and materials forensics in nuclear activity
- Analytical instrumentation and nuclear safeguards
