AB SCIEX QTrap 5500 With Selexion
Type: Triple quadrupole and linear ion trap
Date acquired: 2013
Comments: Fitted with selexION differential ion mobility spectrometry (DMS) device to allow separation of isobaric and co-eluting molecules. This instrument is part of a collaboration with AB Sciex (Toronto, Canada) through the ARC Linkage Program and has been modified to measure Ozone Induced Dissociation (OzID) mass spectra. OzID is a technique developed in our lab and uses a selective reaction between the ion and ozone gas to cleave double bonds and reveal their position(s) within the molecule. OzID is used routinely for structural characterisation of lipids
Sources: Electrospray
Uses: DMS separation of isomeric lipids, OzID for identification of fatty acid double bond position
Additional features: Eksigent ekspert? nanoLC400 system
AB SCIEX QTrap 5500
Type: Triple quadrupole and linear ion trap
Date acquired: 2011
Sources: Electrospray, Advion Nanomate (chip-based nanoESI)
Uses: The instrument is part of the UOW lipidomics facility and is used for the identification and quantification of a wide range of lipids in extracts from diverse sources including tissue, tears and cell culture. The automated nanomate source allows the investigation of large sample arrays
Additional features: Liquid extraction surface analysis (LESA) allowing analysis of molecules directly from a surface

Nuclear magnetic resonance spectrometers
The School of Chemistry is currently equipped with three NMR Spectrometers:
The NMR facility is primarily used by the research students and staff in the School of Chemistry. NMR services for external researchers can also be provided (reasonable charges apply).
We also have access to:
- Bruker 600 NMR spectrometer at UNSW
- Bruker 800 MHz spectrometer at ANU
