Owing to its unique combination of high information content and ease of use, Raman spectroscopy, which uses different vibrational energy levels to excite molecules (as opposed to light spectra), has attracted much attention over the past fifteen years. This book covers all aspects of modern Raman spectroscopy, including its growing use in both the laboratory and industrial analysis.

Spectroscopic methods such as Raman are used to investigate the structure and dynamics of matter. They are essential for the study of the different types of mineral or organic materials produced at the Earths surface or interior. As a result of technological improvements in gratings, detectors, filters and personal computers in the last decade, many micro-Raman spectrometers have become plug-and-play instruments, very easy to use and available at a lower cost than the early Raman microprobes. Thus, many laboratories in Earth Sciences and Cultural Heritage are equipped with these new spectrometers. Commercial, portable Raman spectrometers working in the field have also contributed to the spread of Raman spectroscopy. Poor levels of education in terms of Raman spectroscopy in undergraduate courses in Earth Sciences make it difficult for individuals to obtain information of the highest quality relevant to Earth sciences and Cultural Heritage. This volume is, therefore, timely. Four main topics are addressed: Theory; Methodology, including the instrumentation; Experimental aspects; and Application.

The importance of accurate sample preparation techniques cannot be overstated--meticulous sample preparation is essential. Often overlooked, it is the midway point where the analytes from the sample matrix are transformed so they are suitable for analysis. Even the best analytical techniques cannot rectify problems generated by sloppy sample pretreatment. Devoted entirely to teaching and reinforcing these necessary pretreatment steps, Sample Preparation Techniques in Analytical Chemistry addresses diverse aspects of this important measurement step. These include: * State-of-the-art extraction techniques for organic and inorganic analytes * Sample preparation in biological measurements * Sample pretreatment in microscopy * Surface enhancement as a sample preparation tool in Raman and IR spectroscopy * Sample concentration and clean-up methods * Quality control steps Designed to serve as a text in an undergraduate or graduate level curriculum, Sample Preparation Techniques in Analytical Chemistry also provides an invaluable reference tool for analytical chemists in the chemical, biological, pharmaceutical, environmental, and materials sciences.

With the increasing awareness of food safety and quality, consumers continuously demand the reassurance of origin and content of their foods. Furthermore, manufacturers must be able to confirm the authenticity of components of their products in order to comply with government legislation. Protection of the rights of consumers, genuine food processors, and prevention of fraudulent or deceptive practices and the adulteration of food is an important and challenge facing the food industry. Rapid scientific and technological advances in the determination of food authenticity have taken place in recent years and Modern Techniques for Food Authentication focuses on many of those novel techniques. Including coverage of various spectroscopic technologies, methods based on isotopic analysis and chromatography, DNA, enzymatic analysis, electrophosresis and thermal methods, this book provides a valuable, international resource on the latest developments in food authentication. *A comprehensive overview of authentication techniques and technology *Written by an international group of academic and professional peers *Provides an excellent complement to more general books on food safety

Time of flight secondary ion mass spectrometry, TOF-SIMS, is a highly surface sensitive analytical technique that provides information about composition with submicron lateral resolution. For select materials, TOF-SIMS provides unparalleled sensitivity along with excellent reproducibility, and as a mass spectrometric technique, it also provides excellent specificity. Of the analytical methods available, it is among the most surface sensitive, but the physical principles that underlie it are also the least understood. This volume describes the instrumentation, the physical principles behind the technique to the extent they are understood, and provides a practical approach for the interpretation of TOF-SIMS data. The use of advanced data processing methods such as multivariate statistics are described in a readily approachable manner. Given a basic background in undergraduate chemistry and physics, the book will be of use to any student with an interest in the technique.

A collection of infrared and Raman spectra of 500 natural and synthetic polymers of industrial importance is presented in this book. A large variety of compounds are included, starting with linear polyolefins and finishing with complex biopolymers and related compounds. The spectra were registered using Infrared Fourier Transform Spectrometers in the laboratory of the All-Russia Institute of Forensic Sciences. The IR and Raman spectra are presented together on the same sheet. The accompanying data include general and structure formulae, CAS register numbers, and sample preparation conditions. Features of this book: • Continues the long tradition of publishing specific and standard data of new chemical compounds. • For low-molecular weight substances, complementary IR and Raman spectra are featured on the same sample and printed on the same page. This "fingerprint" data allows the substance of the sample to be identified without doubt. • An important feature of this unique collection of data is the increase in the identification precision of unknown substances. • Peak tables are available in digital (ASCII) format, on a diskette delivered with the book. This allows the user to search for unknowns. • All the spectra in the collection are base-line corrected. This book will be of interest to scientists involved in the synthesis of new polymeric materials, polymer identification, and quality control. Libraries of scientific institutes, research centers, and universities involved in vibrational spectroscopy will also find this collection invaluable.

With the maturation of laser technology in diagnostic and conservation applications, conservation scientists, archeologists, art historians, researchers, and advanced science-oriented students now have the tools necessary for preserving the future of our past-our cultural heritage. Presenting recent developments in the field, Lasers in the Preservation of Cultural Heritage: Principles and Applications addresses the basic concepts of laser applications and supplies case studies of analytical, structural diagnostic, and laser cleaning applications. The book provides a comprehensive presentation of the fundamental principles and applications of modern laser technology in the analysis of composition, diagnostics of structural integrity, and conservation of artworks and antiquities. Beginning with an introduction to the basic techniques used in art conservation and archeology, the book describes the fundamental aspects of laser-matter interactions, emphasizing laser diagnostics and laser processing applications. The next few chapters focus on laser-based spectroscopic techniques for the analysis of the composition of materials in art and archaeology, including laser-induced breakdown, Raman, and laser-induced fluorescence spectroscopic techniques. The book proceeds to highlight nondestructive diagnostic techniques, laser processing applications, laser applications for the cleaning of paintings and stone, and methods for the removal of encrustations. It concludes with case studies for the conservation of materials like parchment, paper, metal, ivory, and wood, and includes conservation approaches for modern paintings. Bridging science with art, Lasers in the Preservation of Cultural Heritage presents a systematic overview of the fundamentals and applications of laser techniques in artwork conservation and archeological science.
