The use of extraction chromatography resins to concentrate actinides and strontium from soil for radiochromatographic analyses

Fit for purpose validated method for the determination of the strontium isotopic signature in mineral water samples by multi-collector inductively coupled plasma mass spectrometry

“…Alternatively, the use of a chromatographic separation is particularly suitable for the elimination of not only Rb but also of other elements present at very high levels, such as Ca (as high as 500 mg L − 1 in some waters qualified as "rich in minerals"). Sr selective extraction can be performed mainly with commercial resins using crown compounds [15,16] or sulfonic acid [17][18][19] as functional groups. The method described in this paper is based on 2 consecutive chromatographic separations followed by multi-collector (MC-) ICPMS measurements and was applied to a batch of 11 commercial mineral waters from France.…”

Separation of actinides at ultra-trace level from urine matrix using extraction chromatography-inductively coupled plasma mass spectrometry

“…The changes in oxidation states for actinides result in different k's on the resin. [23][24][25] Different types and concentrations of acids in the extraction solutions play important roles for the separation as well.…”

Automated ⁹⁰Sr Separation and Preconcentration in a Lab-on-Valve System at Ppq Level

“…On-site measurements of radioactive materials have many benefits and advantages, but there is no application of flow scintillation to 90 Sr monitoring. Basically, quantification is achieved using an online detector that mixes the eluate coming from the LOV device with the scintillating cocktail 11 21 22 . The mixture is then pumped through the counting cell and measurement is made using paired photomultipliers.…”
