G.G. Hatch Stable Isotope Laboratory

University of Ottawa, Ottawa, Ontario
Area(s) of Expertise

The Hatch Laboratory maintains a fleet of gas-source mass spectrometers for analysis of stable isotopes (D, 13C, 15N, 18O, 34S) in environmental samples of minerals, water, gases and organic materials in support of research areas ranging from natural resources to environmental contamination. We offer state of the art analysis in most fields, including sample caraterisation.

What the facility does
