Development of LC-QTOF-MS based workflows for the non-targeted analysis of food contaminants



Food contaminant analysis has benefitted from rapid developments in the fields of chromatography and mass spectrometry, in terms of quantification and sample throughput. In the last decade, the innovation brought by the usage of accurate mass measurements led to a more robust identification of unknown molecules in complex matrices. In this talk, examples will be provided to demonstrate how LC-QTOF-MS can be used to analyze unexpected contaminants present at trace level in food, but is also used as a tool for mining for non-previously reported chemical structures, providing additional key food safety information.



Dr Stéphane BAYEN is Assistant Professor in the Department of Food Science and Agricultural Chemistry at McGill University. His research interests include (i) analytical chemistry applied to the detection of trace contaminants and their metabolites in food and the environment, (ii) the fate of contaminants (contaminant chemistry; bioaccumulation mechanisms involved in the contamination of foodstuff; behavior of contaminants during food storage, processing and cooking) and (iii) ecological & human health risk assessments. Since 2014, he is building a research program at McGill University (, concentrating on developing novel non-targeted approaches (e.g. Foodomics) to monitor contaminants and to provide a more in-depth understanding of their behavior from field to fork.

Groupe de discussion en spectrométrie de masse de Montréal (GDSMM)

Le groupe de discussion sur la spectrométrie de masse de Montréal (GDSMM) est un organisme à but non lucratif qui offre un forum favorisant les interactions locales, nationales et internationales entre les scientifiques oeuvrant en spectrométrie de masse. Le GDSMM organise des séminaires scientifiques et des forums de discussion présentant les derniers développements en recherche fondamentale et appliquée en spectrométrie de masse. Une réunion annuelle du GDSMM qui regroupe les étudiants et les post-doctorants a lieu à Montréal chaque printemps et offre une opportunité unique de réseautage en plus d’accroitre la visibilité et la sensibilisation aux contributions locales en spectrométrie de masse.

Montreal mass spectrometry discussion group (MMSDG)

The Montreal mass spectrometry discussion group (MMSDG) is a not-for-profit organization that provides a forum to promote local, national and international interactions among scientists involved in mass spectrometry. MMSDG sponsors scientific seminars and forums to present the latest developments in basic and applied research in mass spectrometry. An annual MMSDG meeting that regroups students and postdoc is held every spring in Montreal, and provide a unique networking opportunity to participants and enhance the visibility and awareness of local contributions in mass spectrometry.
