The Metabolomics Innovation Centre (TMIC) is Canada’s nationally-funded core facility for metabolomics research. Led by Professor David Wishart from the University of Alberta’s Departments of Biological Sciences and Computing Science, it offers a unique combination of equipment and personnel, capable of performing a wide range of studies aimed at understanding metabolic pathways and the effect or fate of compounds introduced into animals, plants, and insects. TMIC has access to more than $26 million in state-of-the-art infrastructure designed to identify over 2,000 chemicals in biological samples, including a number of SCIEX QTRAP instruments to perform quantitative MS analysis.
David explained: “TMIC is made up of several ‘nodes’ across Canada, with the majority of these located at the University of Alberta. We use a diverse range of MS-based analytical techniques, including GC-MS, LC-MS, CE-MS, and ICPMS – as well as NMR – to look at different analytes, sample types, and sample volumes. We process 5,000 to 10,000 samples a year from across Canada and the USA, as well as for a number of international studies, and our SCIEX QTRAP instruments are our ‘go to’ machines for quantitative metabolic assays; they’re the workhorses of the center.”
“We originally chose the QTRAP systems about 10 years ago. I’d had experience with MS instruments from a variety of manufacturers in a previous role but, coming from an NMR spectroscopy background; I was surprised how delicate they seemed; we spent as much time fixing them as running them. In comparison, our SCIEX QTRAPs are very robust, running almost constantly and requiring only minimal maintenance. This kind of reliability is essential when you’re a core facility offering a service to external clients. The instruments in the QTRAP range are also quite compact – they’re very much benchtop systems – which obviously makes it easier to fit them into the lab, and many of the commercially available metabolomics assays are configured for QTRAP systems, making them the logical choice.”
“OUR SCIEX QTRAP INSTRUMENTS ARE OUR ‘GO TO’ MACHINES FOR QUANTITATIVE METABOLIC ASSAYS; THEY’RE THE WORKHORSES OF THE CENTER.”
“We currently have six QTRAP systems across TMIC, including two 4000 QTRAP Systems in my lab that perform over half of all our quantitative sample analysis. We use a combination of commercial kits and in-house developed assays, and one of the benefits of having a number of instruments from the same manufacturer – and based on the same technology – is that it makes it easier to transfer assays and protocols between labs. To further simplify things, we have developed a number of internal assay kits which, combined with SCIEX’s fairly intuitive software, make it very easy to run the same assay at different nodes within TMIC. This is particularly useful given our fairly high turnover of researchers – a natural consequence of being a university-based facility – making it easier for new users to learn to operate the systems efficiently.”
“Due to the number of external samples we receive for profiling, both 4000 QTRAP instruments are running at full capacity, and so we have recently purchased a QTRAP 5500 System to increase our service capacity and provide more instrument time for research. We will also be using this system to expand our lipid analysis capabilities. Lipids play a central role in metabolomics, but identification and quantification can be very complex. SCIEX’s recent developments in this area – with the Lipidyzer Platform and a number of related protocols – are a real benefit for this work. We have had a number of very positive interactions with the SCIEX team on this subject, and this increased focus on lipid analysis is one of our main reasons for choosing the QTRAP 5500,” David concluded.

As analytical organizations grow, there is an even greater need to train scientists and operators more consistently to meet tight deadlines, handle increasing samples, and meet data quality expectations. A high rate of employee turnover also affects the productivity of labs worldwide. Consistent training helps today’s labs stay competitive, whether the goal is sample throughput, therapeutic development, or publication.
A few years ago, I was plotting along in my analytical job and keeping up-to-date with residue regulations took a considerable amount of time, but it was always manageable. Nowadays, we have PFAS.
Produced by certain moulds, thriving in crops such as grain, nuts and coffee, mycotoxins have contaminated agriculture and food production industries for a long time. To intensify the challenge, mycotoxins are resilient, not easily broken down and ensuring the safety of food supply chains requires comprehensive solutions and we are here to share those solutions with you.
