The Queen’s Mass Spectrometry Facility currently consists of four mass spectrometers.
- Thermo Fisher Orbitrap Velos Pro with an electrospray ionization (ESI), heated-electrospray ionization (HESI), or EASY-nLC nanospray ionization (NSI) probe.
- Applied Biosystems Qstar XL QqTOF mass spectrometer with matrix assisted laser desorption ionization (MALDI) source and electrospray ionization source (ESI).
- GC-TOF mass spectrometer.
- A single quadrupole ZQ-LC/MS mass spectrometer.
The daily operation of the facility is overseen by the MS facility manager, Dr. Jiaxi Wang. This facility provides MS services and expertise for the analysis of small and macromolecules, proteins and enzymes to both users in the Queen’s community and from other institutions and industry. The current users of this facility include Queen’s researchers from Biology, Biochemistry, Cell Biology, Chemistry, Chemical Engineering, Geological Sciences, Immunology, Pharmacology, Microbiology, Pathology and Molecular Medicine, and a large number of researchers from various industries and other universities.

- Thermo Scientific Orbitrap Velos Pro (Easy-nLC/HESI Hybrid Ion Trap-Orbitrap Mass Spectrometer)
- AB Sciex Qsar XL (MALDI/ESI Quadrupole Time of Flight Mass Spectrometer)
- Micromass GCT (GC-EI Time of Flight Mass Spectrometer)
- Micromass ZQ Single Quad (ESI Single Quadrupole Mass Spectrometer)
Organic Analysis Mass Spectrometers:
Thermo Scientific Orbitrap Velos Pro, Qstar XL, GC-TOF and ZQ-MS. EI-GC-TOF Sample introduction on the GC TOF instrument occurs using a probe. The TOF analyzer enables high resolution (5000-7000) mass measurements with an accuracy of ~5 ppm. EI is most suitable for low molecular weight, low polarity compounds (m/z range ~1500).
ESI-Orbitrap Velos Pro:
The Fourier transform (FT) analyzer enables high resolution (up to 100000) mass measurement with an accuracy of less than 3 ppm. The HRMS for the analysis of mixtures can be obtained with combination of nLC and Orbitrap. The excellent mass accuracy (< 3 ppm with external calibration and < 1 ppm using internal calibration) allows us to give possible molecular formula.
Liquid chromatography mass spectrometry (LCMS)
The nLC-Orbitrap Velos Pro Supports qualitative and quantitative applications with low limits of detection.

Mass Range Consideration
- Electron impact (EI) MS: 50-800 Da
- Low resolution ESI MS: 50- 2000 Da
- High resolution ESI MS: 50-70,000 Da
- High resolution MALDI MS: 600-40,000 Da
- High resolution MS/MS: 100-6000 Da
Selecting an Ionization Method
- EI: Stable, volatile samples (under high vacuum, up to heat at 350 degrees)
- ESI: Complex (such as organometallic compounds), non-volatile, thermally labile or unstable samples
- MALDI: organic polymers and biomolecules
MS samples are normally analyzed in the positive ionization mode because of high sensitivity, except some analysis of organic acids, sugars, nucleic acids have to be performed in negative ionization mode.
Solubility of Organic Compounds
Although EI MS samples can be submitted in either solid or liquid form, ESI MS analysis needs a soluble sample to be tested prior to submission. The best solvents used in MS analysis are recommended to be methanol, water, acetonitrile, or their combination, and samples dissolved in THF, methane chloride, DMSO are also acceptable.
Proteins should be desalted with a dialysis in 10 mM ammonium bicarbonate solution or centrifugal filter in an appropriate MW cut-ff membrane tube. Coomassie stained gel bands of proteins from SDS-PAGE gels are submitted in centrifugal tubes without water, and labeling of sample names must be clearly present.
Please note the facility will not accept Bio-hazardous or Radio active labeled samples.
