Near Infrared Technology

Imagine an analytical technique that uses no chemicals, gives accurate and precise results in minutes or even continuously, and is simple to install and safe to use. Near-infrared spectroscopy (NIRS) supplies this dream. This book covers all of the essential features for successful NIRS application in a practical and easily understandable format. The driving force behind compiling this book is to provide knowledge on all aspects of NIRS to potential users, and to users who would like to delve a little deeper into the technology. We have assembled the book, mainly to help in the application of near-infrared (NIR) instruments and technology in industry.

This reference gives food science professionals a working understanding of near-infrared spectroscopy (NIRS) and its role in maximizing food potential. It explains the technical aspects of NIRS, including: basic principles; characteristics of the NIR spectra; instrumentation; sampling techniques; and chemometrics. The book details applications of NIRS in agricultural and marine products, foodstuffs and processed foods, engineering and process monitoring, and food safety and disease diagnosis.

This book summarizes the results of the NATO Advanced Research Workshop on "Syntheses, Optical Properties, and Applications of Near-Infrared (NIR) Dyes in High Technology Fields" held at Trest (Czech Republic) from September 24 to 27, 1997. It was attended by 52 scientists from 16 countries, among them 18 participants from 8 Eastern-Europe. The Workshop has been stimulated by the great progress that has been made in utilizing NIR dyes in high technology areas. This has been triggered by the availability of reliable. vel)' small, and inexpensive laser diodes emitting in the NIR region which raise the analytical detection limits by several orders of magnitude, allow time-resolved measurements for temporal discrimination between spectrally similar species, and make possible miniaturization as well as remote sensing through space and by fiber optical techniques. Furthermore, NIR dyes proved to be vel)' important in other high technology fields such as laser physics, optical recording techniques, nonlinear optics, biochemistty and medicine.

This book provides knowledge of the basic theory, spectral analysis methods, chemometrics, instrumentation, and applications of near-infrared (NIR) spectroscopy—not as a handbook but rather as a sourcebook of NIR spectroscopy. Thus, some emphasis is placed on the description of basic knowledge that is important in learning and using NIR spectroscopy. The book also deals with applications for a variety of research fields that are very useful for a wide range of readers from graduate students to scientists and engineers in both academia and industry. For readers who are novices in NIR spectroscopy, this book provides a good introduction, and for those who already are familiar with the field it affords an excellent means of strengthening their knowledge about NIR spectroscopy and keeping abreast of recent developments.

Over the last few years, near-infrared (NIR) spectroscopy has rapidly developed into an important and extremely useful method of analysis. In fact, for certain research areas and applications, ranging from material science via chemistry to life sciences, it has become an indispensable tool because this fast and cost-effective type of spectroscopy provides qualitative and quantitative information not available from any other technique. This book offers a balanced overview of the fundamental theory and instrumentation of NIR spectroscopy, introducing the material in a readily comprehensible manner. A considerable part of the text is dedicated to practical applications, including sample preparation and investigations of polymers, textiles, drugs, food and animal feed. However, special topics, such as two-dimensional correlation analysis, are also covered in separate chapters. Written by eight experts in different fields, this book presents an introduction to the current state of developments and is valuable to spectroscopists and to practitioners applying NIR spectroscopy as a daily analytical tool.

This volume explores developments in techniques in diagnostics, DNA sequencing, bioanalysis of immunoassays, and single-molecule detection. It promotes the measurement, identification, monitoring, analysis, and application of near-infrared spectroscopy (NIR) to medical and pharmaceutical advances. The text also considers noninvasive methods of NIR for successful, cost-effective, and prompt diagnoses of diseases.
