Welcome to the Environmental Isotope Laboratory

The University of Waterloo Environmental Isotope Lab is now receiving samples. 

Please be aware that there may be delays in sample analysis. Please do not send samples to the EIL until the required chemistry is available as they cannot be prioritized or analyzed until it is received. 

Thank you for your patience as we work hard to implement new COVID-19 safety protocols and implement operational measures to protect EIL staff and others. We will continue to provide updates when available.

The University of Waterloo-Environmental Isotope Laboratory (UW-EIL), a research group within the Department of Earth and Environmental Sciences, develops and applies isotope technology to the Environment.

Founded in 1971 by Dr. Peter Fritz, the UW-EIL offers analysis for the isotopes of a number of elements including hydrogen (δ2H, 3H), carbon (δ13C, 14C), nitrogen (δ15N), oxygen (δ18O), sulphur (δ34S), chlorine (δ37Cl), bromine (δ81Br) and strontium (87Sr/86Sr) for a wide variety of applications. UW-EIL is today an innovative modern research facility with an international client base encompassing universities, government agencies, consulting firms and other institutions.
