According to a study from Lausanne, Switzerland, "Plutonium and americium are radionuclides particularly difficult to measure in environmental samples because they are alpha-emitters and therefore necessitate a careful separation before any measurement, either using radiometric methods or ICP-SMS. Recent developments in extraction chromatography resins such as Eichrom [R] TRU and TEVA have resolved many of the analytical problems but drawbacks such as low recovery and spectral interferences still occasionally occur."
"Here, we report on the use of the new Eichrom [R] DGA resin in association with TEVA resin and high pressure microwave acid leaching for the ...
