Established in 1859, the University of Toronto’s Department of Chemistry is one of the leading and recognized institutions in Canada. We take pride in our teaching excellence, advanced research facilities, and development of distinguished scientists in the past and for the future. Our department has a wide variety of services including chemical stores, NMR lab, X-Ray analysis lab, and a Mass Spectrometry lab.

These resources, combined with our ambition and excitement, create an ideal place to work, research, and make an impact in scientific education.


Your opportunity:

Under the general supervision of the Analytical Facility Manager in the Advanced Instrumentation for Molecular Structure (AIMS) Facility, the Mass Spectrometry Specialist assists in the operation of the Mass Spectrometry core analytical facility by analyzing samples using chromatography and mass spectrometry instrumentation. These duties include acquisition, processing, interpretation, error checking and reporting of mass spectral data for a variety of samples (e.g. small organic molecules, proteins, peptides, oligonucleotides, organometallics, carbohydrates, organic polymers etc.)

using a variety of ionization sources (e.g. EI, CI, ESI, DART, MALDI, etc.) and a variety of mass spectrometers (e.g. quadrupole, time-of-flight, etc.). The Mass Spectrometry Specialist provides services such as interpretation of mass spectra, HRMS determinations, isotopic purityanalysis and GC-MS/LC-MS analyses. The Specialist is also responsible for maintaining sample records, performing routine instrument maintenance and calibration, adhering to quality control procedures and ensuring a safe working environment.


Your responsibilities will include:

• Performing lab experiments that requires great precision and attention to many details
• Analyzing data
• Ensuring that the material needs of laboratory exercises and/or courses are available
• Constructing proof of concept experiments to test different elements of the process
• Preparing, assembling and setting-up material, equipment and supplies used in teaching and/or research labs
• Coordinating routine maintenance of lab equipment
• Providing safety training and ensuring compliance to lab safety procedures and standards
• Serving as a technical resource on laboratory protocols, and experimental procedures and equipment

Essential Qualifications:

• Master's Degree in Chemistry or an acceptable combination of equivalent experience and education.
• Minimum 3 years of recent and relevant experience in the field of mass spectrometry, including demonstrated experience operating, maintaining, and troubleshooting a variety of mass analyzers (e.g. quadrupole, time-of-flight, ion trapping, etc.) with a variety of ion sources (EI, CI, ESI, DART, MALDI, etc.).
• Experience with GC-MS and HPLC-MSmethod development and implementation.
• Demonstrated experience in maintaining and troubleshooting instruments, including scanning electron microscopy (Quanta 250 FEG FEI Environmental SEM, Hitachi HT7700) and Transmission Electron Microscopy (FEI Tecnai TF20)
• Specific knowledge and understanding of the theory and principles of mass spectrometry and separation science pertaining to chemical…
