Isotope analysis

  • The variation of isotope ratios is increasingly used to unravell natural and technical questions. In the past the investigation and interpretation of such variations was the field of a limited number of experts. With new upcoming techniques and research topics in the last decades, such as provenance and authenticity of food, the number of published isotope data strongly increased. Instrumental developments such as the enhancement of inductively coupled plasma mass spectrometers (ICPMS) from an instrument for simple quantitative analysis to highly sophisticated isotope ratio machines influenced this process significantly. While in former times only experts in mass spectrometry were able to produce reliable isotope data, nowadays many laboratories, never been in touch with mass spectrometry before, produce isotope data with an ICPMS. Especially for such user isotope reference materials (IRM) are indispensible to enable a reliable method validation.

Especially for such user isotope reference materials (IRM) are indispensible to enable a reliable method validation. The fast development and the broad availability of ICPMS also lead to an expansion of the classical research areas and new elements are under Investigation. This presentation shows the basics and principles for isotope ratio determination using ICP-MS. Additionally, it provides three specific examples for isotope Ratio applications: isotope dilution mass spectrometry; provenancing of archaeoligical artifeacts by lead isotope Ratio Analysis and studies on boron uptake in bell pepper plants.zeige mehrzeige weniger
