This book contains a selection of papers and articles in instrumentation previously pub lished in technical periodicals and journals of learned societies. Our selection has been made to illustrate aspects of current practice and applications of instrumentation. The book does not attempt to be encyclopaedic in its coverage of the subject, but to provide some examples of general transduction techniques, of the sensing of particular measurands, of components of instrumentation systems and of instrumentation practice in two very different environments, the food industry and the nuclear power industry. We have made the selection particularly to provide papers appropriate to the study of the Open University course T292 Instrumentation. The papers have been chosen so that the book covers a wide spectrum of instrumentation techniques. Because of this, the book should be of value not only to students of instrumen tation, but also to practising engineers and scientists wishing to glean ideas from areas of instrumentation outside their own fields of expertise. In recent years instrumentation has emerged as a discipline in its own right rather than as an adjunct to traditional science and engineering disciplines. This development has been driven partly by the needs of industries for new and improved sensing techniques, and partly by new technological developments such as microprocessors, optical fibres and in tegrated silicon sensors which are revolutionising sensing and signal processing practice.

Analytical Instrumentation examines analyzers for detecting pollutants and other hazardous matter, including carbon monoxide, chlorine, fluoride, hydrogen sulfide, mercury, and phosphorous. Also covers selection, application, and sampling procedures.

Intended for both the novice and professional, this text aims to approach problems with currently available tools and methods in the modern analytical chemistry domain. It covers all fields from basic theory and principles of analytical chemistry to instrumentation classification, design and purchasing. This edition includes information on X-ray methods and analysis, capillary electrophoresis, infrared and Raman technique comparisons, and more.

Instrument Technology, Volume 2: On-Line Analysis Instruments describes a variety of on-line analysis instruments used in measuring the quality of products, including sampling systems for gases and liquids; on-line instruments for ASTM procedures; and instruments for measuring density or specific gravity, humidity, chemical composition, and viscosity. Measurements employing nuclear techniques are also considered. This text is comprised of seven chapters. After giving an introduction that explains the importance of analysis instruments and their applications in a wide range of industries, the book turns to sampling systems for gases and liquids. The next chapter focuses on instruments for measuring density and specific gravity of liquid, such as static-pressure-operated mechanisms (for example, gas purge systems), weighing tube types, buoyancy types, recording hydrometers, totally immersed displacer types, and acoustic resonance types. Measurements employing nuclear techniques such as radio-isotopes are then described, along with instruments used to measure Reid vapor pressure, distillation characteristics, pour point, flash point, cloud point, and octane number. Finally, this book discusses instruments used to measure chemical composition and viscosity. The use of non-dispersive infrared analyzers in chemical plants is highlighted. This book will be useful not only for chemists and instrument and chemical engineers, but also for prospective instrument technicians.

This valuable resource covers the principles of analytical instrumentation used by today's chemists and biologists and presents important advances in instrumentation, such as the drive to miniaturise and lab-on-a-chip devices. In terms of the lab-based analytical instrumentation, the five main categories of technique—spectroscopic, chromatographic, electrochemical, imaging and thermoanalytical, are included and presented in a practical, not theoretical way. Including relevant examples and applications in a number of fields such as healthcare, environment and pharmaceutical industry this book provides a complete overview of the instruments used within the chemistry industry, making this an important tool for professionals and students alike.
