Introduction to mass spectrometryMass spectrometry is an analytical technique which can be used for the identification, quantification and some structural , qelucidation of compounds. It does this through measurement of the mass to charge ratio of gaseous ions.
Identification – you can use this to determine what your reaction products are…
MSMS Quantification – you can use this to determine absolute yield or to investigate changes in metabolism for example – cancer metabolites. Whole PhD…
Structural studies –fragmentation studies using MS can lead g gto information about the structure – often used in conjunction with NMR

Becoming a trained user
1. Discuss and agree your needs for MS with your supervisor.
2 Email or come and see Dr James McCullagh who will2. Email or come and see Dr James McCullagh who will arrange the training (~2 hours).
3. This will enable you to book and use the instrument unsupervised.
4. You may not use any trained user instrument unless you have received training from a member of the MS staffhave received training from a member of the MS staff.

Protocol and Safety• No lab coats to be worn in any of the MS labs.
• Never remove or modify any part of the mass spectrometer system, sample inlet system or software. If something is not working properly please report to a member of the ms facilityworking properly please report to a member of the ms facility staff.
• Data you are responsible for you own data management. When using any instrument (except the open access) make sure you remove all your own data from the instrument y ycomputer hard drive within at least 1 week of acquisition. You may keep this data on MassStore.
• Please read safety information on the mass spectrometry website and all information provided at Mass Spectrometer t i lterminals.
