TRU Resin
Extraction Chromatographic Resin
TRU Resin
Core Applications
Complete actinide separation (U, Th, Pu, Np, Am, Cm)
Separation of trivalent actinides (Am³⁺/Cm³⁺) from lanthanides (Ln)
Highly selective separation of Fe (III) (for ⁵⁵Fe analysis)
Determination of total transuranic element content in environmental, geological, and nuclear waste samples
Key Advantages
Unique full actinide coverage
Simultaneous adsorption of U/Th/Pu/Np/Am/Cm for one-step enrichment
Efficient trivalent actinide/lanthanide separation
High separation factor between Am and light lanthanides (La–Eu)
Strong Fe (III) specificity
No adsorption under low acid conditions, direct elution possible, suitable for ⁵⁵Fe analysis
Good matrix tolerance
No impact from high salt, high iron, high aluminum, or organic matter on adsorption
Mature standard procedures
Can be used in combination with UTEVA, TEVA, and LN resins to form a complete actinide separation system
