Polycyclic aromatic hydrocarbons (PAHs) are the first type of chemicals that were ever discovered to cause cancer in humans. They are found in cigarette smoke, in barbecued and smoked foods, in automobile and Diesel engine exhaust, fireplace smoke, and many other common things that people are exposed to. Analyzing for PAHs in the environment is important in identifying potential sources of cancer exposure and eliminating these as risks. The smaller PAHs, those of lower than 300 molecular weight, have been the most studied and have also been covered in several books. No books have dealt with the analysis of the larger PAHs. These compounds are not only important for the health concerns, but they are also of current technological and scientific interest.

Commercial Biosensors offers professionals an in-depth look at some of the most significant applications of commercially available biosensor-based instrumentation in the medical, bioprocess, and environmental fields. Featuring contributions by an international team of scientists, the book provides readers with an unparalleled opportunity to see how their colleagues around the world are using these powerful new tools. Commercial Biosensors is divided into three sections. In the first, which is devoted to applications of biosensors to clinical samples, the authors explore how biosensors are currently being used for in-home diabetes monitoring, point-of-care diagnostics, and noninvasive sensing, and biomedical research. The second section deals with cutting-edge applications of biosensors in bioprocess control- for example, measuring glucose, sucrose, glutamate, or choline concentrations during food and beverage production and measuring ethanol concentration during beer fermentation. In the final section, readers learn about the use of biological oxygen demand (BOD) biosensors for monitoring environmental samples. This book is an indispensable addition to the reference libraries of biosensor technologists, physicians, analytical chemists, environmental engineers, pesticide chemists, clinical chemists, and food chemists. An in-depth exploration of state-of-the-art commercial biosensor technology and its aplications. Commercial biosensor technology has taken off over the past few years, and the number of applications is growing rapidly. This book offers professionals a timely and authoritative look at some of the most important of these applications. Over the course of seven chapters authored by leading international experts, readers learn all about the latest in: * Biosensors and diabetes management * Microfabricated biosensors and point-of-care diagnostics systems * Noninvasive biosensors in clinical analysis * Surface plasmon resonance and evanescent wave biosensors * Biosensor-based instruments in food and beverage production * Biosensors in environmental sampling Commercial Biosensors is required reading for all professionals who would like to take advantage of the enormous potential of one of today's most important new commercial technologies.

Research and development of solid state gas sensor devices began in the 1950s with several uncoordinated independent efforts. The number and pace of these investigations later accelerated in response to increasing pressure placed on the environment and public health by industrial activities. Since 1970, several thousand articles have been written on the subject, and laboratories around the globe have introduced novel methodologies and devices to address needs associated with particular technological developments. Despite the rapid development of this important new technology, very little has been done to review and coordinate data related to sensor science and technology itself. Physics, Chemistry and Technology of Solid State Gas Sensor Devices focuses on the underlying principles of solid state sensor operation and reveals the rich fabric of interdisciplinary science that governs modern sensing devices. Beginning with some historical and scientific background, the text proceeds to a study of the interactions of gases with surfaces. Subsequent chapters present detailed information on the fabrication, performance, and application of a variety of sensors. Types of sensor devices discussed include: Gas-sensitive solid state semiconductor sensors Photonic and photoacoustic gas sensors Fiber optic sensors Piezoelectric quartz crystal microbalance sensors Surface acoustic wave sensors Pyroelectric and thermal sensors For analytical chemists using solid state sensors in environment-related analysis, and for electrical engineers working with solid state sensors, this book will expand and unify their understanding of these devices, both in theory and practice.

A bestselling classic reference, now expanded and updated to cover the latest instrumentation, methods, and applications The Second Edition of Fourier Transform Infrared Spectrometry brings this core reference up to date on the uses of FT-IR spectrometers today. The book starts with an in-depth description of the theory and current instrumentation of FT-IR spectrometry, with full chapters devoted to signal-to-noise ratio and photometric accuracy. Many diverse types of sampling techniques and data processing routines, most of which can be performed on even the less expensive instruments, are then described. Extensively updated, the Second Edition: * Discusses improvements in optical components * Features a full chapter on FT Raman Spectrometry * Contains new chapters that focus on different ways of measuring spectra by FT-IR spectrometry, including fourteen chapters on such techniques as microspectroscopy, internal and external reflection, and emission and photoacoustic spectrometry * Includes a new chapter introducing the theory of vibrational spectrometry * Organizes material according to sampling techniques Designed to help practitioners using FT-IR capitalize on the plethora of techniques for modern FT-IR spectrometry and plan their experimental procedures correctly, this is a practical, hands-on reference for chemists and analysts. It's also a great resource for students who need to understand the theory, instrumentation, and applications of FT-IR.
