A novel and simple analytical procedure has been developed for the trace-level determination of lanthanides (rare-earth elements) in uranium-bearing materials by inductively coupled plasma sector-field mass spectrometry (ICP-SFMS). The method involves a selective extraction chromatographic separation of lanthanides using TRU™ resin followed by ICP-SFMS analysis. The limits of detection of the method...
An improved and novel sample preparation method for 241 Am analysis by inductively coupled plasma sector field mass spectrometry has been developed. The procedure involves a selective CaF 2 pre-concentration followed by an extraction chromatographic separation using TRU™ resin. The achieved absolute detection limit of 0.86fg (0.11mBq) is comparable to that of alpha spectrometry (0...
