Isotopic measurements using ICP-MS: a tutorial review

Abstract

The isotopic information provided by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is revised from a tutorial point of view covering both the use of enriched stable isotopes and the measurement...

High-resolution continuum source graphite furnace molecular absorption spectrometry for the monitoring of Sr isotopes via SrF formation: a case study

“…Generally, these analyses are carried out with dedicated instruments based on mass spectrometry (MS), which stand out for their high sensitivity and selectivity. 1 In particular, the application of inductively coupled plasma mass spectrometry (ICP-MS) to this eld needs to be highlighted, as this technique enables getting access to isotopic information for a large number of elements at trace and ultratrace levels, thus offering very relevant data for all the scien-tic elds previously discussed, 7 and also when only elemental information is aimed at, either in real samples 8 or for the certication of reference materials, 9 via isotope dilution. When high-precision isotopic information is required (e.g., for monitoring isotopic variations involving non-radiogenic nuclides), the use of multi collector ICP-MS devices is typically needed.…”

Atomic spectrometry update – a review of advances in environmental analysis

“…A tutorial review (136 references) on isotopic measurements by ICP-MS covered 267 the use of enriched stable isotopes and the measurement of natural variations in elemental isotopic composition. These two fields of study are often treated separately in the literature even though they share many fundamental principles.…”

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

“…Additionally, a section was included that itemised a series of tests to assess accuracy, robustness and precision of the isotopic measurements. A tutorial-style review of isotopic measurement by ICP-MS was completed by Penanes et al 156 This covered two aspects of isotopic measurement: natural variations in the isotopic composition of the elements, and the use and measurement of enriched stable isotopes used as tracers. Guidance and equations for isotope abundance calculations, delta values, mass bias, isobaric/polyatomic interferences, blanks and memory effects were covered in the first part of the review.…”
