High-precision iron isotopic measurements in low resolution using collision cell (CC)-MC-ICP-MS

Abstract

Here we present an analytical method for Fe isotopic measurements in low resolution mode, using a Nu Sapphire collision cell-equipped multi-collector inductively coupled plasma mass spectrometer by standard-sample bracketing. High...

(LA)-MC-ICPMS/MS measurement of Sr radiogenic isotope ratios

“…The introduction of SF 6 decreases the transmission by half (56.2%, 55.5%, and 54.3% for 86 Sr, 87 Sr, and 88 Sr, respectively, residual 84 Sr being undetectable) and allows the conversion of more than 95% of Sr into SrF (95.3%, 95.4%, and 95.6% for 86 Sr, 87 Sr, and 88 Sr, respectively). In addition to the formation of sulfur tetrauoride at 108 amu, the introduction of SF 6 generates an isobaric interference of 32 S 19 F 3 16 O + on the high-mass shoulder of 88 SrF at 107 amu (Fig. 3A), which tends to shrink over time but remains signicant (Fig.…”

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…When comparable conditions were used, external precision of the measurements were found to be better than ±0.03& (2 sd) for d 56 Fe. Wang et al 180 used a collision-cell equipped Nu Sapphire MC-ICP-MS to make Fe isotope measurements in a low-resolution mode. Helium and H 2 were added to the hexapole collision cell, where H 2 was a reaction gas for charge exchange with interfering argide species.…”

“…The same research group also developed a technique for precise measurement of Fe isotopes and provided Fe isotopic data for twenty‐one geological RMs (Wang et al . 2022b). Zhu et al .…”
