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.

Perkin Elmer Nexion 350X Inductively Coupled Plasma Mass Spectrometer (ICPMS)

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.

Perkin Elmer Nexion 2000B Inductively Coupled Plasma Mass Spectrometer (ICPMS)

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 (28KB, pdf) 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.

The charges (per sample) for services performed by the Mass Spectrometry Facility are listed below:

	School of Chemistry	The University of Sydney	Non-University of Sydney
Low resolution ESI/APCI/APPI/Solid probe/EI/CI/GCMS	$15	$30	$60

¹Special rates will also apply for investigators involved in the ARC LIEF grant used to obtain the FTICR.

²NexION 350X School of Chemistry price is also for School of Geoscience. NexION 2000B School of Chemistry price is also for all members of Sydney Nano and this cost does not include calibration standards required for analysis.

Other services such as extensive sample preparation, data interpretation, LC/MS, MS/MS, MALDI imaging etc. will be charged by the hour in negotiation with Mass Spectrometry staff. External invoices will include an additional 10% GST charge. The costs of analysis may be discussed with the staff of the Mass Spectrometry Facility.

Non-University of Sydney charges apply to all external users, whether affiliated to the School/University or not. They also apply to any contract research or consultative work performed by members of the School or University. If in doubt, it may be discussed with the staff of the Mass Spectrometry Facility.

The facility operates on a subsidised cost recovery basis for Australian academic and government clients, and on a full cost recovery basis for others. The PPMS is charged in 24-hour blocks (10am-10am) or part thereof.  

The other instrument charges are per peak hour, Mon-Fri, 9am-5pm. After-hours/weekend (building access only available to University of Sydney Chemistry staff and students) rates are half peak hour rates. Overnight (5pm-9am) costs the same as two peak hours. Charges listed below are for instrument use only. Extra Staff Scientist's time for training in the use of the instruments and services such as running your samples for you, filling nitrogen dewars, etc. will be charged at $50/h for University of Sydney users and $100/h for external clients.  

	PPMS daily	Dynacool PPMS daily	Versalab hourly	TGA	DSC	ITC
USyd chemistry Staff/students*	$150	$200	$20	$9	$9	$9
Other USyd users	$200	$300	$40	$15	$15	$15
External clients (+GST)	$450	$550	$60	$30	$30	$30

* Internal USYD user rates will apply to external CIs on the relevant ARC LIEF

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.

The facility currently contains six PowerEdge R730 nodes as its primary compute workforce each with 24 cores, 128 GB RAM and 20Gbe networking connections. 

The facility also contains more than 35TB of shared storage on the dedicated network attached storage.

Numerous chemistry simulation packages are installed on the HPC cluster and requests can be made to install additional software.
