Abstract:

Stable isotopic analysis is an important branch of analytical chemistry. Accurate determination of the stable isotopic compositions of substances is critical for tracing their sources and investigating their transformation processes. The new generation of mass spectrometry technology has greatly facilitated the development of high-precision stable isotopic analysis methods. In particular, multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) has emerged as a powerful tool for isotopic composition determination. However, isotopic analysis by MC-ICP-MS is highly sensitive to the sample matrix, which may compromise the precision and accuracy of the analysis. Therefore, it is particularly important to reduce the sample matrix effect using efficient sample purification techniques. This article summarizes the recent progress in sample purification and instrument hyphenation methods for MC-ICP-MS, and provides perspectives on the future application of MC-ICP-MS in different fields.

Key words: multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS), ion-exchange chromatography (IEC), isotopic analysis, sample purification, hyphenated technology
