The use of ICPMS for stable isotope tracer studies in humans: a review.

The use of stable isotope tracers in human studies is a rapidly growing research field that benefits from the many new developments in inorganic mass spectrometric instrumentation and from the better availability of mass spectrometric techniques to nutritional scientists during the last three decades. Traditionally, thermal ionization mass spectrometry (TIMS) has been the preferred technique for these studies, but the development of new inductively coupled plasma mass spectrometric (ICPMS) techniques with better isotope-ratio measurement and interference-removal capabilities (e.g. single and multi-detector ICPMS and reaction/collision cell ICPMS) has enabled broader use of ICPMS for determination of stable isotope tracers in nutritional research. This review discusses the current and future use of ICPMS in stable isotope tracer studies in humans. [ABSTRACT FROM AUTHOR]
