Our Expertise

Mass Spec's expertise comes from key members of the forensic scientific community

Richard Sleeman BSc (Hons), PhD, CSci, CChem, FRSC, MFSSoc: Scientific Director 

Dr Sleeman is one of the founders of Mass Spec Analytical Ltd. and currently holds the position of Scientific Director. Dr. Sleeman obtained his PhD from the University of Bristol. He is a member of the Academy of Experts, and has been a Law Society Checked Expert Witness since 1997. 

For most of his career he has specialised in the detection of trace quantities of drugs and explosives. He has published over thirty scientific papers and articles on trace detection. He has been closely involved in the development of the techniques and methodologies employed in the examination of drugs traces on paper currency, and has presented such work in Court on approaching one hundred occasions, including at the Court of Appeal on three occasions. Dr. Sleeman’s areas of expertise include trace drugs and explosives evidence, mass spectrometry (MS), ion mobility spectrometry (IMS), and blood alcohol calculations.

Mr John George Luke: Company Secretary, Business & Engineering Director 

John Luke is a founding director and Business Manager of Mass Spec Analytical Ltd. He is an Aerospace Engineer who worked as a Project Manager for various British Aerospace projects. He is entirely familiar with the procedures and protocols consistent with the economic and efficient execution of business practices. Within MSA, he has controlled several projects simultaneously, involving overseas and UK customers and suppliers.

Mr. Luke was responsible for the design and manufacture of MSA’s boarding pass analyser prototypes, and all of the MSMS front-end introduction units, including related control and other supporting equipment developed at MSA to date. Mr Luke has also adapted MSA design introduction units to function successfully with alternative design mass spectrometers.

He continues to be involved with various ongoing research projects and most recently has completed a prototype high volume trace vapour collection and detection system, suitable for the detection of explosives, drugs or other illicit substances in cargo.

Vicki Rowsell BSc (Hons) Biochemistry: Forensic Scientist

Vicki joined MSA in 2012 after working for the Forensic Science Service for 12 years. She has experience of testing exhibits suspected to contain controlled drugs using TLC, GCMS, HPLC and FTIR. She has also compared packaging to help establish whether or not different seizures of drugs were from a common source.

Her work at MSA, in addition to drugs analyses, has also included analysis of RTA samples (blood and urine for alcohol levels).

The majority of her work now involves using tandem mass spectrometry to detect trace amounts of drugs. She also has the responsibility of managing MSA's quality systems.






Byron Morgan BSc (Hons), MCSFS, MRSC: Senior Forensic Scientist

Byron has worked with Mass Spec Analytical since 2011 when he completed his final year project for his degree with us. He gained a First Class Honours Degree (BSc, Forensic Science) at the University of The West of England, Bristol, in 2011, and he is a Professional Member of  the Chartered Society of Forensic Sciences and the Royal Society of Chemistry. He is also a member of the British Mass Spectrometry Society. He is active in R&D projects, has published publications regarding his work and has given talks about our evidence.  He has attended courses on Mass Spectrometry and statistics.

Byron is now employed as a Senior Forensic Scientist and the majority of his work involves the use of tandem mass spectrometry for the identification of trace amounts of illicit drugs on banknotes and various other items.

Byron has analysed thousands of exhibits, has written statements relating to the forensic analyses he has performed, and has appeared as an expert witness in court on numerous occasions.

Elizabeth Drake BSc (Hons), MSc, MFSSoc, MRSC: Forensic Scientist 

Elizabeth Drake has been employed as a Forensic Scientist by MSA since 2005, prior to this she worked as an industrial technician in the chemical industry. She was awarded a BSc in Chemistry with Industrial Experience from the University of Wales, Cardiff, and has since continued her professional development as a member of the Forensic Science Society, the British Mass Spectrometry Society and the Royal Society of Chemistry, for which she is currently working towards chartered status.

Elizabeth specialises in using tandem mass spectrometry for the identification of trace amounts of illicit drugs. She also has experience in other analytical techniques including GC-FID, GC-MS and FTIR. She routinely analyses items for traces of illicit drugs and documents her findings in statements and reports. She regularly attends court as a prosecution expert witness.

Peter Luke: Senior Engineer 

Peter joined MSA in 2002 after an 18-year career as an electrical engineer. In his time at MSA, Peter has been involved in a number of key international projects involving MSA’s mobile mass spectrometer detection system, the Scentinel. 

The projects have involved Peter designing and developing core equipment and peripherals, and assisting and supporting the deployment of the equipment around the world. He is MSA’s designated field engineer and is responsible for working on the maintenance contracts MSA has with its Scentinel customers.

Peter has trained US airport workers, Police Officers in the UK, army personnel in Northern Ireland, and government officials in the UK and USA, to use the equipment in a variety of detection scenarios. Peter has extensive experience in the maintenance and use of Sciex API Triple Quadrupole mass spectrometers and the related operating software; the Analyst.
