Book excerpt: Experiments done at very early times, less than 1 \U+00b5\s, confirmed the presence of plasma conditions sufficient to induce Thomson Scattering in a LIBS plasma but the satellite peaks could not be observed. Plasma temperature measurements with multi-element aerosols revealed a distinctive change in the slope of the temperature curve; this reflects the effects on local plasma cooling on plasma properties. A change in the matrix of the aerosols resulted in measurable shifts in the temporal temperature profile. Overall, the current set of experiments shows the strong dependence of the LIBS signal on plasma-particle interactions and highlights the need for a complete understanding of this phenomenon. Finally, additional experiments are proposed to further facilitate this understanding.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Critical understanding of plasma-particle interactions includes study of the plasma evolution, analyte atomization, and the particle dissociation and diffusion. In this dissertation, temporal and spatial studies have been done to understand the fundamentals of the LIBS processes including the breakdown of gases by the laser pulse, plasma inception mechanisms, plasma evolution, analyte introduction and plasma-particle interactions and their influence on LIBS signal. Spectral measurements were performed in a laser-induced plasma and the results reveal localized perturbations in the plasma properties in the vicinity of the analyte species, for first 60 [mu]s. The measurements provide direct evidence of matrix effects in the LIBS plasma at early times. Electron density measurements at very early times in the plasma reveal deviations from the Local Thermodynamic Equilibrium conditions (LTE). The data from various experiments suggests a complex interaction between the plasma and the aerosol particle, during which the finite time-scales of particle dissociation, and heat and mass transfer are fundamental processes.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Laser-Induced Breakdown Spectroscopy (LIBS) is a powerful and well-established atomic emission diagnostic for the identification and analysis of unknown samples. Recent research efforts have shown that LIBS is useful for both qualitative identification and for the quantitative measurement of relative as well as absolute analyte concentration regardless of analyte state. More recently, much interest has been directed toward the use of LIBS in the analysis of aerosol systems, including those generated by laser ablation (LA-LIBS). While LIBS offers many advantages as a diagnostic tool, there are several difficulties that limit its capability and robustness. Chief among these are matrix effects and incomplete or inhomogeneous sample vaporization. In an effort to fully understand, and eventually mitigate, these difficulties, the current work seeks to design and implement a numerical model that describes the complex plasma-particle interactions that govern the LIBS of aerosol systems. The model incorporates the processes of heat transfer, hydrodynamics, mass diffusion, vaporization, and electromagnetism. The model considers the fundamental physics of three distinct regimes: the global plasma environment, the local particle behavior, and the initial nature of plasma inception.

Book excerpt: ABSTRACT: The physical and optical characteristics of laser-induced plasmas (LIP) and the precision of measurements using laser-induced breakdown spectroscopy (LIBS) for aerosol and gas phase species are explored. In a series of coherent experiments properties of the LIP and the temporal, spatial, and energetic variations of interactions with entrained particles (aerosols) are evaluated from both a standpoint of basic plasma science and applied atomic spectroscopy. First, the evolution of a LIP is characterized in terms of its temporally-resolved spectral absorptivity, spectral emissivity, and free electron density during the first 500 nanoseconds. Transmission measurements reveal near opacity of the LIP at early times (10-50 ns) and essential transparency at longer times (500 ns).

Book excerpt: Laser-Induced Breakdown Spectroscopy, Second Edition, covers the basic principles and latest developments in instrumentation and applications of Laser Induced Breakdown Spectroscopy (LIBS). Written by active experts in the field, it serves as a useful resource for analytical chemists and spectroscopists, as well as graduate students and researchers engaged in the fields of combustion, environmental science, and planetary and space exploration. This fully revised second edition includes several new chapters on new LIBS techniques as well as several new applications, including flame and off-gas measurement, pharmaceutical samples, defense applications, carbon sequestration and site monitoring, handheld instruments, and more. LIBS has rapidly developed into a major analytical technology with the capability of detecting all chemical elements in a sample, of real- time response, and of close-contact or stand-off analysis of targets. 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

Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive source of the fundamentals, process parameters, instrumental components and applications of laser-induced breakdown spectroscopy (LIBS). The effect of multiple pulses on material ablation, plasma dynamics and plasma emission is presented. A heuristic plasma modeling allows to simulate complex experimental plasma spectra. These methods and findings form the basis for a variety of applications to perform quantitative multi-element analysis with LIBS. These application potentials of LIBS have really boosted in the last years ranging from bulk analysis of metallic alloys and non-conducting materials, via spatially resolved analysis and depth profiling covering measuring objects in all physical states: gaseous, liquid and solid. Dedicated chapters present LIBS investigations for these tasks with special emphasis on the methodical and instrumental concepts as well as the optimization strategies for a quantitative analysis. Requirements, concepts, design and characteristic features of LIBS instruments are described covering laboratory systems, inspections systems for in-line process control, mobile systems and remote systems. State-of-the-art industrial applications of LIBS systems are presented demonstrating the benefits of inline process control for improved process guiding and quality assurance purposes.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the characteristics of optical radiation, or a spectrum, emitted by various plasmas. In plasma, the same atomic species can produce quite different spectra, or colours, depending on the nature of the plasma. This book gives a theoretical framework by which a particular spectrum can be interpreted correctly and coherently. The uniqueness of the book lies in its comprehensive treatment of the intensity distribution of spectral lines and the population density distribution among the atomic levels in plasmas. It is intended to provide beginners with a good perspective of the field, laying out the physics in an extremely clear manner and starting from an elementary level. A useful feature of the book is the asterisked sections and chapters which can be skipped by readers who only wish to gain a quick and basic introduction to plasma spectroscopy. It will also be useful to researchers working actively in the field, acting as a guide for carrying out experiments and interpreting experimental observations.
