Regional Mass Spectrometry Centre
The mass spectrometry facility at University de Montréal features state-of-the-art instrumentation for addressing analytical needs in organic, inorganic, environmental, and biological chemistry.
PRESENTATION
Our specialists collaborate to provide both technical guidance and services including:
- High throughput accurate mass measurement
- Structure confirmation by MS/MS
- Mass determination on macromolecules
- Quantification and separation of mixtures by LCMS
Analyses offered by the mass spectrometry laboratory
- Determination of nominal mass - available ionisation sources: ESI, APCI, APPI
- Accurate mass analysis (m/z 50-8000) - available ionisation sources: ESI, APCI, APPI
- Analysis of high molecular weight molecules (proteins, polymers) - available ionisation sources: ESI
- Fragmentation pattern generation and analysis on MS/MS spectra (peptides and small molecules) - available ionisation sources: ESI
- Preparatory LC on reversed phase with fraction collection (collection triggered by mass, UV signal or retention time)
- Analysis of complex mixtures by tandem separation: LC-MS, LC-MS/MS
- Chiral and achiral separations by SFC-MS and/or SFC-UV
- Chiral preparatory SFC with fraction collection triggered by UV
Submission procedure
Submission of samples for accurate mass analysis
Samples should be submitted as approximately 0.1 mg/mL solutions. The most suitable solvents are water, methanol, acetonitrile and dichloromethane. Total sample volume could vary between 0.1 and 1.5 ml. If you need to use other solvents (DMSO for example) or if you dispose of sample volumes smaller than the previously mentioned limit, ask for assistance.
Appropriate vials are available in Room B-4077 of the MIL campus.
Please fill-up the online form for each submitted sample.
Submission of samples for SFC
For analytical SFC analyses, the samples should be submitted as a solution around 1 mg/mL. The accepted solvants are methanol, isopropanol and hexanes. Samples containing water, DMF, DMSO or DCM are not suitable for analysis.
For preparative SFC, please submit samples neat.
Please fill-up the online form for each submitted sample.
