Applications of stable isotopes in mass spectrometry

Gunda Köllensperger, Institut für Analytische Chemie, Universität Wien

Stable isotopes have become an indispensable tool for accurate absolute quantification and tracer studies in mass spectrometry. The presentation will cover applications of elemental speciation analysis and metabolomics, reflecting the state of the art of isotope dilution mass spectrometry addressing the complementary approaches, namely ICP-MS and ESI-MS based analysis (both in combination with chromatographic separation systems).
Analytical figures  of merit  of the  different methods  will  be discussed with  regardto isotope ratio measurement precision and – as a consequence – measurement uncertainty. The concept of in vivo synthesized isotopically enriched 34S and 13C standards will be highlighted.
