Housed within the School of Chemistry, our research infrastructure is supported by dedicated high-level professional and technical expertise.
The Mass Spectrometry Facility in the School of Chemistry provides analytical services for researchers within the school, other researchers at the University of Sydney, as well as users outside the University.
There are six mass spectrometers in the Facility and low resolution and high-resolution spectra can be obtained by most ionisation techniques. Two instruments are jointly administered with other departments.
The amaZon is a quadrupole ion trap mass spectrometer obtained in 2015. The mass range of this instrument is m/z 50-4000 and the ion trap is ideally suited for MS/MS and MSn experiments with fast polarity switching. Ionisation modes available include ESI, APCI (liquid and direct probe), APPI (liquid and direct probe), online nanospray source (Captivespray nanoBooster source) and a home-built offline nanospray source. The mass spectrometer can be connected to an Agilent 1100 HPLC with binary pump, diode array detector and column heater.
The Clarus SQ 8 C is a quadrupole mass spectrometer obtained in 2016 with a mass range of m/z 4-1000 in full scan or selective ion mode. Ionisation modes include EI and CI using methane as the reactive gas. The mass spectrometer is connected to a Clarus 680 GC which can perform automated liquid injections, manual headspace and manual SPME injections.
This Matrix Assisted Laser Desorption Ionization – Time of Flight (MALDI-TOF) mass spectrometer was obtained in 2015. This instrument can operate in linear (1-300,000 Da) or reflectron mode. The mass spectrometer is equipped with a TLC-MALDI holder and flexImaging software to allow MALDI-imaging experiments for TLC/tissue samples prepared in Sydney Mass Spectrometry. It is capable of performing high energy MS/MS experiments using post source decay either with or without a collision cell. Polymerix software to aid in co-polymer interpretation and biotools for proteomic analysis are also available.
The 7 Tesla FTICR was commissioned in late 2018. This high resolution (450,000 @ 1Hz and 400 m/z, 20,000,000 maximum resolving power) instrument has an actively shielded, refrigerated superconducting magnet allowing a mass accuracy of 600ppb. It is equipped with an ESI/MALDI dual source and has a nanospray (Captivespray nanoBooster source), a home-built offline nanospray source, APCI and APPI (dissolved and solid probe) ionisation methods either via syringe infusion or connection with a Waters Acquity UPLC H-Class with PDA detector. Fragmentation options include CID (in source, in collision cell or in ICR cell), ECD and ETD. SciLS software is available to allow visualisation of MALDI-FTMS imaging experiments for TLC/tissue samples prepared in Sydney Mass Spectrometry.
The Perkin Elmer Nexion 350X Inductively Coupled Plasma Mass Spectrometer was purchased and commissioned in 2015 by the School of Geosciences and is jointly administered between the School of Geoscience and School of Chemistry. It is an instrument used to measure trace concentrations of metals and some non-metals. This instrument is set-up to handle liquid samples; therefore most samples will require pre-treatment/acid digestion and/or dilution prior to analysis. The benefits of this instrument include rapid multi element quantitative analysis, very low limits of detection, isotopic analysis and a wide dynamic range. It is equipped with universal cell technology and has Kinetic Energy Discrimination (KED) available to allow removal of molecular interferences. It is equipped with a 240-sample position autosampler for 10mL sample tubes.
The Perkin Elmer Nexion 2000B Inductively Coupled Plasma Mass Spectrometer was purchased and commissioned in 2018 by Sydney Nano, and is jointly administered between Sydney Nano and School of Chemistry. It is an instrument used to measure trace concentrations of metals and some non-metals. This instrument is set-up to primarily handle nanoparticles (characterisation of particle size distributions), cell culture samples (determination of attogram abundance of a metal in individual cells) or bacteria cultures. It is equipped with an ESI SC-µ DX autosampler capable of running samples off a 96 well plate or 2mL tubes.
The Mass Spectrometry Facility provides analytical services for organic compounds, biochemical compounds and organo-metallic compounds. To submit a sample, please fill out the Sample Submission Form and send it with the sample to the Mass Spectrometry Facility, Room 223, Madsen Building, F09 The University of Sydney, NSW, 2006 by mail or in person.
To obtain a mass spectrum, the sample must first be ionized. The ionization techniques available in the Unit are EI, CI, MALDI, ESI and APCI at present. Each technique has its own advantages and limitations. Please consult the staff in the facility if you cannot decide which of the techniques would be suitable for your sample.
Samples should be submitted in a sample screw-cap vial or 1.5 mL Eppendorf tube labelled with a sample identification code. About 0.1 mg to 1 mg of solid or liquid samples is required. For normal EI or CI MS, solvent free and pure samples are preferred because solvents or impurities may suppress the peaks of interests and complicate the structure analysis. For MALDI, ESI, APCI, GC/MS or LC/MS, please specify solvent. For samples requiring GC/MS analysis, a GC trace and the column conditions should be provided, if possible.

A relatively small extra charge, our cost price, may need to be applied for clients who use substantial quantities of consumables (e.g. PPMS VSM sample tubes are $11 each, DSC pans are $4 each.
Most DSC measurements require LN2. One 50L dewar will support several measurements - 50 litre, LN2 dewar $50 – including Staff Scientist time to fill it.
All charges apply regardless of the "success" of the experiment.
