Joint Mass Spectrometry Facility

An initiative of the Research School of Chemistry and Research School of Biology in partnership with CSIRO Black Mountain Campus

The Joint Mass Spectrometry Facility (JMSF) was created in 2016 by the Research School of Chemistry and Research School of Biology to consolidate and grow mass spectrometry facilities at the ANU.  In partnership with the CSIRO Black Mountain campus, the JMSF is supporting research in the greater Canberra region as an important aspect of the Science and Industry Endowment Fund (SIEF) supported Analytical Precinct.

The JMSF is focusing on three main application areas using a variety of mass spectrometry instruments.  These application areas include:

  • Metabolomics
  • Proteomics
  • Synthetic (single) molecule characterisation

People

Dr Stephen Watt
Manager, Joint Mass Spectrometry Facility

Dr Watt has a background in biological mass spectrometry having completed his PhD at the University of Wollongong under the supervision of Professor Jenny Beck and Professor Margaret Sheil.  Stephen undertook a Post Doctorate Placement at the University of Oxford before working for the instrument supplier, Waters, as an applications chemist in discovery proteomics and metabolomics. Recently, Stephen worked for the Australian Sports Anti-doping Authority (ASADA) as the Science and Results Manager.  Dr Watt has extensive experience in in biological mass spectrometry, particularity in the characterisation of proteins and peptides.  Additionally with this knowledge of mass spectrometry he is able to advice on the use of equipment to obtain the most out of a given experiment.

Ms Anitha Jeyasingham
Head, RSC Mass Spectrometry Facility

Mrs Anitha Jeyasingham did her B.Sc. (Honours) at the University of Jaffna, Sri Lanka. After working as an academic in Sri Lanka, she was awarded the prestigious NZODA scholarship to do her M.Sc. at the University of Waikato, New Zealand followed by employed as an Organic Analyst at Hill Laboratories.  Shortly after she was promoted to analytical division, which introduced her into the world of Mass spectrometry.

After migrating to Australia in 2004, she joined the Mass Spectrometry unit at the Research school of chemistry.  Stemming from her work in New Zealand, Anitha specializes in synthetic small organic molecule analyses. She provides and maintains a high ratio of comprehensive analytical support to over 20 research groups in RSC, RSB and surrounding area, in particular in reaction monitoring, identification, accurate mass measurements, purity checks and characterisation of synthetic compounds.

The research interests of RSC varies extensively and synthesize very small, volatile and unstable organic compounds to very big macro-cyclic compounds. 

Dr Thy Truong
Mass Spectrometry Officer

Dr Thy Truong completed her PhD (Analytical and Environmental Chemistry, 2001) at RMIT University focusing on lipid biomarkers to distinguish sources of faecal pollution in contaminated waters and sediments around popular tourist hotspots in the East Gippsland Lakes, Victoria. She also developed new optimised analytical techniques for analysing and quantifying lipid markers using multidimensional GCxGC with cryogenic trapping and GC-MS. She undertook a postdoctoral research associate position (substituting for a Senior Research Scientist as the head of the research project and the organic chemistry laboratory) at the Stroud Water Research Center in Pennsylvania investigating the use of molecular tracers for monitoring sources of contamination in streams and rivers associated with the New York City drinking water system (Safe Drinking Water Act grant funded by the U.S. EPA and the New York State Department of Environmental Conservation). In 2003 she worked as a postdoctoral fellow at RMIT University to derive a holistic approach to managing dairy processor waste streams before working as a postdoctoral fellow at the University of Melbourne investigating the environmental inorganic chemistry of phosphorus and arsenic in aquatic and terrestrial ecosystems using flow injection analysis with membrane separation and spectrophotometric or chemiluminescence detection. She then decided to gain experience in commercial FDA/NATA accredited chemical testing laboratories as an analytical chemist at Cardinal Health (pharmaceuticals), and OMIC Australia (food). Her position at CSIRO Materials Science and Engineering (April 2008 - July 2010) as an Environmental Analytical Chemist and Deputy Laboratory Manager in the Environmental Analysis Group (EAG) reignited her interests in research and method development/validation in analytical chemistry, separation science and mass spectrometry, which in turn has led her to her appointment as RSB Mass Spectrometry Officer (February 2011 - present).

Equipment

The Joint Mass Spectrometry facility is equipped with a number of instruments to facilitate the analysis of a variety of compounds:

Synthetic (single) molecule characterisation

Waters LCT Premier
Description: The LCT Premier orthogonal acceleration time-of-flight (OA-TOF) mass spectrometer features a Z-Spray source with electrospray ionisation (ESI) and modular LockSpray interface. The TOF analyzer utilizes W-Optics, a novel method for enhancing resolution.
Uses:  This system is used for accurate mass measurements of organic and inorganic compounds and the intact mass measurements of proteins and peptides.

Micromass/Waters ZMD
Description: The Waters/Micromass ZMD is a single quadrupole benchtop Mass spectrometry detector that couples to an alliance HPLC system.  The system uses electrospray ionisation to transfer ions into the gas phase.
Uses:  This system is used for the low resolution analysis of organic and inorganic compounds in an open access environment.

Micromass/Waters AutoSpec Premier
Using Electron ionisation (EI) or Chemical ionisation (CI) this system analyses non-polar synthetic compounds in low and high resolution to obtain elemental compositions and accurate mass measurements.

Agilent GC-MS (5073)
Description: One dimensional Gas phase Chromatography inlet with Electron Ionisation and tandem low resolution quadrupole analyser.  
Uses: This instrument is currently used as a walk-up instrument for synthetic chemist to screen products from synthetic molecule reactions.

Metabolomics

Agilent GC (7890A)/MS (5975) with Gerstel MultiPurpose Sampler
Description: One dimensional Gas phase Chromatography inlet with Electron Ionisation (EI) or Chemical Ionisation (CI) and tandem low resolution quadrupole analyser.  
Uses: this system is used for a variety of metabolomics applications which harness the Gerstel system for automation in sample preparation and delivery to the GC-MS.

Agilent 7010 GC-MS/MS 
Description: One dimensional Gas phase Chromatography inlet with Election Ionisation and tandem low resolution quadrupole analyser.  
Uses: This instrument is able to undertake MS2 experiments, multiple reaction monitoring (MRM) and Pseudo MS3 experiments to add specificity to complex samples.  

Agilent 6120 single Quad with Agilent 1260/1290 LC
Description: One dimensional Liquid Chromatography inlet with electrospray ionisation and a low resolution single quadruple analyser.  
Use: This instrument is currently being used for natural product analysis to monitor enzymatic reactions.

Thermo Q Exactive Plus with UHPLC
Description: This instrument couples an analytical flow UHPLC with Orbitrap technologies.  Mass selection with the quadruple analyser of the Q Exactive plus facilitates tandem (MS/MS) analysis to better characterise and target analytes of interest. 
Uses: This system is used for metabolomics applications in both discovery and targeted modes of operation.

Proteomics

ABI-Sciex 4800 
Description: Matrix Assisted Laser Desorption Ionisation (MALDI) – Time-of-Flight – Time-of-Flight Mass spectrometer.
Uses: This instrument offers a platform of simple proteomics experiment including in-gel spot identification or protein sequencing using bottom up approaches. Polymer analysis is also conducted with this system.
