Welcome to our lab!

The University of Ottawa is proud to announce the establishment of the André E. Lalonde Accelerator Mass Spectrometry (AMS) Laboratory for the analysis of isotopes at very low concentrations in natural materials and for research into new techniques and applications of this technology. Funds for the laboratory were provided by the Canada Foundation for Innovation, the Ontario Innovation Foundation and the University of Ottawa along with contributions of equipment from the University of Toronto and Health Canada. The Lalonde Laboratory is located in uOttawa’s new Advanced Research Complex (ARC), a state-of-the-art, open-concept, research-only building designed to integrate students and researchers from across Canada and the world and to foster innovation and interdisciplinarity in the Geosciences and Photonics.


Our instrument

The cornerstone of the laboratory is a custom-built 3 MV tandem accelerator mass spectrometer manufactured by High Voltage Engineering. It has been designed to analyze an array of isotopes, including 3H, 10Be, 26Al, 36Cl, 129I, 236Uand, of course, 14C. In addition, a second injector line, the uOttawa Innovation line, will integrate new AMS technologies, such as the use of low energy ion-gas reaction cells to eliminate interferences from atomic isobars and the use of photonic selection techniques. The spectrometer, located adjacent to the ARC's glazed entrance foyer, is a central feature which highlights the technology of Canada's only AMS to our students – our next generation of researchers.
