Investigations for determination of Gd and Sm isotopic compositions in spent nuclear fuels samples by MC ICPMS

In situ Nd isotopic measurement of natural geological materials by LA-MC-ICPMS

“…Unlike the recommended value, the newly obtained 147 Sm/ 149 Sm ratio of 1.08680 [17] and 144 Sm/ 149 Sm ratio of 0.22332 [18] determined by MC-ICPMS are used for the isobaric correction of 144 Sm on 144 Nd in this study. This approach is almost the same as that of 176 Yb on 176 Hf during in situ zircon Lu-Hf isotopic analysis [15,19,20] .…”

Repeated kimberlite magmatism beneath Yakutia and its relationship to Siberian flood volcanism: Insights from in situ U–Pb and Sr–Nd perovskite isotope analysis

“…During our study, the mass bias of Sm (ß Sm ) was directly obtained from the interferencefree 147 Sm/ 149 Sm ratio of the unknowns and then applied in the isobaric interference correction following the method of McFarlane and McCulloch (2007). The 147 Sm/ 149 Sm ratio of 1.08680 (Dubois et al, 1992) and 144 Sm/ 149 Sm ratio of 0.22332 (Isnard et al, 2005) were used for correction. The in-house AFK perovskite standard was used for the external corrections of 147 Sm/ 144 Nd and 143 Nd/ 144 Nd (cf., Fisher et al, 2011;Iizuka et al, 2011).…”

Determination of 90Sr/238U ratio by double isotope dilution inductively coupled plasma mass spectrometer with multiple collection in spent nuclear fuel samples with in situ 90Sr/90Zr separation in a collision-reaction cell

“…Instrumental mass fractionation is corrected with a ''standard-sample bracketing'' approach which involves the measurement of an internal standard (NIST 987) between samples and using an exponential law fractionation [26]. The mass discrimination for Sr is corrected externally by measuring the 86 Sr / 88 Sr ratio, due to the fact that the average mass between 86 Sr / 88 Sr and 84 Sr / 90 Sr are the same [27]. The standard and the sample are analyzed at the same concentration.…”
