Accelerator mass spectrometry as a bioanalytical tool for nutritional research

Adv Exp Med Biol. 1998;445:397-410. doi: 10.1007/978-1-4899-1959-5_25.

Abstract

Accelerator Mass Spectrometry is a mass spectrometric method of detecting long-lived radioisotopes without regard to their decay products or half-life. The technique is normally applied to geochronology, but is also available for bioanalytical tracing. AMS detects isotope concentrations to parts per quadrillion, quantifying labeled biochemicals to attomole levels in milligram-sized samples. Its advantages over non-isotopic and stable isotope labeling methods are reviewed and examples of analytical integrity, sensitivity, specificity, and applicability are provided.
