O autorze

John R. Dean took his first degree in Chemistry at UMIST, followed by an M.Sc. in Analytical Chemistry and Instrumentation at Loughborough University of Technology and finally a Ph.D. and D.I.C. in Physical Chemistry at Imperial College. He then spent 2 years as a postdoctoral research fellow at the Food Science Laboratory of the Ministry of Agriculture, Fisheries and Food in Norwich in conjunction with Polytechnic South West in Plymouth. The work was focused on the development of directly coupled high performance liquid chromatography inductively coupled plasma mass spectrometry methods for trace element speciation in foodstuffs. This was followed by a temporary lectureship in Inorganic Chemistry at Huddersfield Polytechnic. In 1988 he was appointed to a lectureship in Inorganic/Analytical Chemistry at Newcastle Polytechnic (now Northumbria University). This was followed by promotion to Senior Lecturer (1990), Reader (1994) and Principal Lecturer (1998). In 1998 he was awarded a D.Sc. (London) in Analytical and Environmental Science and was the recipient of the 23rd SAC Silver Medal in 1995. He has published extensively in analytical and environmental science. He is an active member of the Royal Society of Chemistry Analytical Division having served as a member of the atomic spectroscopy group for 15 years (10 as honorary secretary) as well as a past chairman (1997–99). He has served on Analytical Division council for three terms and is currently its vice–president (2002–04) as well as chairman of the North East Region (2001–03).

Blurb

This text provides a valuable and readily accessible, practical introduction to inductively coupled plasma spectroscopy, serving both as a basic textbook for taught courses and also as a self–study resource for those pursuing open learning/distance learning forms of study.

Topics covered within this essential text include:

• Methodology for trace elemental analysis
• Sample preparation techniques for inductively coupled plasma spectroscopy, including those used for aqueous and solid samples, plus details of the various extraction procedures that can be used to prepare samples
• Sample introduction procedures for plasma sources
• The inductively coupled plasma and other sources used for atomic emission spectroscopy and mass spectrometry
• Fundamental aspects of atomic emission spectroscopy and mass spectrometry
• Spectrometers and detectors used for plasma spectroscopy
• Interferences in atomic emission spectroscopy
• Principles of inductively coupled plasma mass spectrometry (ICP MS)
• Types of mass spectrometers used for ICP MS
• Interferences in ICP MS and their remedies, including collision/reaction cells
• Isotope dilution analysis
• A range of applications for this technique, including forensic science, industrial analysis, clinical/biological analysis, materials analysis, environmental analysis, food analysis and pharmaceutical analysis
• Sample data sheets that can be used to record information in the laboratory
• A comprehensive bibliography, providing information on how to keep up–to–date with the latest developments in this field, guiding the reader to more specialized texts and sources, including books, journals and recommended  web sites

Practical Inductively Coupled Plasma Spectroscopy will be invaluable to those students studying at Foundation and BTEC (HNC and HND) levels, and for those pursuing BSc, MChem, MSc and MRes courses in analytical chemistry, as well as subsidiary courses in life, environmental and food science. In addition, it will be a useful guide to those using ICP, and related techniques, in applied research and analysis.
