Development of a single method for direct measurement of multiple radionuclides using ICP-MS/MS

Abstract

Simultaneous radionuclide measurement in a single procedure using tandem mass spectrometry contributing to rapid, cost-effective nuclear decommissioning and environmental monitoring.

Assessing Gas-Phase Ion Reactivity of 50 Elements with NO and the Direct Application for 239Pu in Complex Matrices Using ICP-MS/MS

“…Previous literature , used the sensitivity of 238 U + in MS/MS mode with 12 mL/min He for 238 U total . However, this method of calculating hydride removal does not account for ion transmission losses that occur when introducing reaction gases at higher flows. ,,, …”

“…However, this method of calculating hydride removal does not account for ion transmission losses that occur when introducing reaction gases at higher flows. 33,35,36,44 To show the utility of NO for 238 U 1 H + interference removal, various concentrations of 239 Pu (0.05−0.5 pg/g) were analyzed in a matrix containing 50−5000 ng/g of 238 U. Table S6 shows the determined concentrations of each solution analyzed, along with the ratio of Pu/U.…”

An isotope dilution mass spectrometry overview: tips and applications for the measurement of radionuclides

“…ICP-MS is widely used for actinide (U, Pu, Am) analyses of biological samples 241,246,247,249–270 with calibration methods that rely on an actinide isotope that is absent from the sample, such as 233 U for U isotopes ( 234 U, 235 U, 236 U and 238 U), 242 Pu for Pu isotopes ( 239 Pu, 240 Pu, and 241 Pu) or 243 Am for 241 Am analysis. Ni et al .…”

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…Russell et al demonstrated how ICP-MS/MS could be used for simultaneous measurement of multiple medium and long-lived radionuclides in a single run without prior sample preparation. 171 The method was tested on a range of aqueous samples and solid digests using various exemption limit criteria, which showed that radionuclides with relatively short half-lives, e.g. 63 Ni and 90 Sr, required pre-concentration and separation prior to measurement.…”
