Resolving isobaric interference in the determination of Nd isotopes using laser ionisation mass spectrometry towards atom percent fission measurements

Abstract

Use of LIMS for determination of Nd in the presence of Sm.

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

“…A problem with 148 Nd is an isobaric interference with 148 Sm, which generally requires chemical separation prior to mass spectrometric measurement. A study by Janardhanan et al 176 examined the potential for direct measurement by LIMS. This involved tuning laser parameters to generate NdO + while leaving Sm as an elemental ion which eliminated the isobaric interference.…”
