Canadian Centre for Electron Microscopy (CCEM)

McMaster University, Hamilton, Ontario
What the facility does

Materials characterization and consultation to determine structural and compositional information on the micron to nano/atomic-scale using electron and ion microscopy

Area(s) of Expertise

The Canadian Centre for Electron Microscopy (CCEM) is a one-stop solution to materials characterization problems. Our experienced and dedicated staff are here to help determine structural and compositional information of material through their advanced knowledge in electron microscopy. Not only does the CCEM offer a suite of electron microscopes and sample preparation space that can be used for characterization needs, but our staff members are fully equipped and available to train users, acquire various data, prepare characterization reports, and consult on user’s specific questions.

As a user’s facility we offer training services on our instruments, or if preferred, we can perform full sample characterization starting from sample preparation to final results. To facilitate our user’s learning experience and networking, we also host various tutorials and workshops throughout the year. Our vision is to be one of the leading electron microscopy facilities in the world for the quality of the scientific research and for promoting interactions amongst researchers in various fields nationally and internationally.
