The IsoTrace (ISOTope and Rare Atom Counting Equipment) Laboratory is a multi-disciplinary centre, established at the University of Toronto, for research in the ultra-high sensitivity analysis of materials using Accelerator Mass Spectrometry (AMS), and for the development of new apparatus and procedures for use in this field.

As a national facility, IsoTrace makes the results of this research and development available as analytical services to a wide range of academic, government, industrial and commercial researchers, in fields such as archaeology, biology, chemistry, earth and environmental science, materials analysis, medicine and physics.
