It does not require any sample preparation, unlike conventional spectroscopic analytical techniques. Samples in the form of solids, liquids, gels, gases, plasmas, and biological materials (like teeth, leaves, or blood) can be studied with almost equal ease. This comprehensive reference introduces the topic to readers in a simple, direct, and accessible manner for easy comprehension and maximum utility. - Covers even more applications of LIBS beyond the first edition, including combustion, soil physics, environment, and life sciences - Includes new chapters on LIBS techniques that have emerged in the last several years, including Femtosecond LIBS and Molecular LIBS - Provides inspiration for future developments in this rapidly growing field in the concluding chapter

Download or read book State of the art Laser Gas Sensing Technologies written by Yufei Ma and published by MDPI. This book was released on 2020-03-05 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace gas sensing technologies are widely used in many applications, such as environmental monitoring, life science, medical diagnostics, and planetary exploration. On the one hand, laser sources have developed greatly due to the rapid development of laser media and laser techniques in recent years. Some novel lasers such as solid-state, diode, and quantum cascade lasers have experienced significant progress. At present, laser wavelengths can cover the range from ultraviolet to terahertz, which could promote the development of laser gas sensing technologies significantly. On the other hand, some new gas sensing methods have appeared, such as photothermal spectroscopy and photoacoustic spectroscopy. Laser spectroscopy-based gas sensing techniques have the advantages of high sensitivity, non-invasiveness, and allowing in situ, real-time observation. Due to the rapid and recent developments in laser source as well as the great merits of laser spectroscopy-based gas sensing techniques, this book aims to provide an updated overview of the state-of-the-art laser gas sensing technologies.

In addition, it explains the selectivity, sensitivity, and stability of the measurements, the construction of databases, and the automation of data analysis by machine learning. Part two explores laser spectroscopy techniques, including cavity-based absorption spectroscopy and the use of photo-acoustic spectroscopy to acquire absorption spectra of gases and condensed media. These chapters discuss imaging methods using laser-induced fluorescence and phosphorescence spectroscopies before focusing on light detection and ranging, photothermal spectroscopy and terahertz spectroscopy. Part three covers a variety of applications of these techniques, particularly the detection of chemical, biological, and explosive threats, as well as their use in medicine and forensic science. Finally, the book examines spectroscopic analysis of industrial materials and their applications in nuclear research and industry.

This book was released on 1996-01-12 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique guide to the application and theory of photothermalspectroscopy. This book debunks the myth that photothermal spectroscopy is toocomplicated for practical application to chemical analysis, anddemonstrates the advantages this technique has over conventionalspectroscopy in facilitating extremely sensitive measurements ofoptical absorption in homogeneous media. The book covers thesubject from the ground up, lists all practical considerationsneeded to obtain accurate results, and provides a working knowledgeof the various methods in use--including photo acoustics andphotopyroelectric techniques. Bringing together a wealth of information that has been scatteredthroughout the professional literature, Photothermal SpectroscopyMethods for Chemical Analysis covers methods and information thatshould be known to every analytical chemist, including: * Descriptions of photothermal spectroscopy using a consistentmathematical language * Helpful examples from the literature of analytical applicationsand current research * Illustrations of all important points, consistent equations, andnumerous original figures * A discussion of laser technology and how it is used to obtainaccurate results from extremely small samples of a few molecules * Everything spectroscopists need to know to construct their ownapparatus and use it to conduct successful experiments * Tips on how to interpret experimental results effectively whenusing nonlinear processes and in many other situations inphotothermal spectroscopy * Considerations for further study of heterogeneous sampleanalysis * Unified nomenclature of the patchwork of terms used byresearchers in analytical and physical chemistry, physics, andoptical engineering * Equations that are derived with the aid of a symbolic languageprocessor to ensure correct results Photothermal spectroscopy has seen major advances since the adventof laser technology twenty-five years ago. It is now possible,using a laser's coherent and powerful output, to obtain extremelysensitive measurements of optical absorption that exceed those ofmass spectroscopy by two or three times, and produce accurateresults from only a few molecules. Focusing on samples in homogeneous media, this book provides aunique guide--incorporating theory and application--to allavailable photothermal spectroscopy techniques for chemical andmaterial analysis. It uses a systematic approach in itscomprehensive treatment of the theory, and covers all the necessarybackground material, from laser optics to fluid dynamics. This accessible text describes the various processes used to detectthermal perturbation of a sample, ranging from optical excitationto nonlinear processes, and covers all optical principles necessaryto understand photothermal spectroscopy. When dealing withhydrodynamic equations that govern energy transfer in the samplematrix, it provides an original impulse-response approach. Inaddition, the book explains how to construct the apparatus oneneeds to conduct successful photothermal experiments, sincecommercial equipment is not available as in conventionalspectrophotometry. Throughout, this book draws on information from a wide range offields, including analytical spectroscopy, measurement physics,physical optics, and chemical dynamics. Providing clearexplanations at every turn, the author demonstrates a completeunderstanding of the theory and applications as a firm basis forthe correct interpretation of experimental results. For analytical chemists, as well as for students at the graduatelevel, Photothermal Spectroscopy Methods for Chemical Analysis isan unmatched resource that develops a consistent mathematical basisfor signal description, consolidates previous theories, andprovides invaluable insight into laser technology.
