Professor Colin Creaser
Emeritus Professor of Analytical Chemistry
Colin Creaser was educated in Uganda and in the UK, at Lancing College and the University of Kent. He has held appointments at the University of California at Santa Barbara; the AEA Harwell Laboratory; the University of East Anglia and Nottingham Trent University. He was appointed Professor of Analytical Chemistry at Loughborough University in 2007 and was awarded the title of Emeritus Professor in 2017. He is an active member of the British Mass Spectrometry Society (BMSS Chair/Vice-Chair, 2013-15; Papers Secretary, 2012-14) and is a member of the BMSS Advisory Board. He is a Fellow of the Royal Society of Chemistry and a Chartered Chemist (FRSC, CChem), and served as President of the Analytical Division and Chair of the Analytical Chemistry Trust Fund from 2002-2004. He is currently Chair of the RSC Analytical Methods Committee and a Trustee of the associated Analytical Methods Trust. The Analytical Methods Committee co-ordinates the activities of analytical scientists associated with seven Expert Working Groups and liaises, on behalf of the RSC, with designated external representatives concerned with the development, validation and standardization of methods of analysis.
Ion mobility and mass spectrometry
The development and application of ion mobility spectrometry (IMS) and field asymmetric waveform ion mobility spectrometry (FAIMS)/differential mobility spectrometry (DMS) as gas-phase electrophoretic separation techniques combined with mass spectrometry (MS). Of particular interest is the development of miniaturised FAIMS combined with mass spectrometry and tandem DMS-MS configurations.
Biomarker discovery and validation
Ion mobility/mass spectrometry methods are applied to targeted and non-targeted metabolomics for the discovery and validation of biomarkers (metabolites that vary in concentration in biofluids, such as saliva, urine and plasma, in response to disease or physiological state). Combining ion mobility spectrometry with mass spectrometry reduces background interferences, increases the number of compounds detected in biofluids and facilitates the separation of isomeric and isobaric compounds not resolved by mass spectrometry alone.
