Book excerpt: ABSTRACT: The goal of this research program was to develop the method of laser-induced breakdown spectroscopy (LIBS) for applications in the phosphate industry. This would include rapid elemental analysis for P, Mg, Si and Fe in materials at various stages of phosphate mining and processing, using off-line, at-line and on-line measurement approaches. Several experimental systems were developed and evaluated. A research instrument with a high resolution spectrometer and gated, intensified CCD detector was used for initial fundamental studies.

This book was released on 2022-12-13 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive overview of recent advances in the area of laser-induced breakdown spectroscopy (LIBS), focusing on its application to biological, forensic and materials sciences. LIBS, which was previously mainly used by physicists, chemists and in the industry, has now become a very useful tool with great potential in these other fields as well. LIBS has a unique set of characteristics including minimal destructiveness, remote sensing capabilities, potential portability, extremely high information content, trace analytical sensitivity and high throughput. With its content divided into two main parts, this book provides not only an introduction to the analytical capabilities and methodology, but also an overview of the results of recent applications in the above fields. The application-oriented, multidisciplinary approach of this work is also reflected in the diversity of the expert contributors. Given its breadth, this book will appeal to students, researchers and professionals interested in solving analytical/diagnostic/material characterization tasks with the application of LIBS.

Book excerpt: Laser-induced plasma spectroscopy (LIPS) is a powerful tool for the multi-element analysis of a huge variety of solid, liquid, and gaseous samples of industrial relevance. For LIPS an intense, pulsed laser beam (typically a Nd:YAG or excimer laser) is focused on the sample of interest, resulting in an evaporation, atomization, and partial ionization of the sample in an expanding plasma cloud. After a delay of some hundred nanoseconds to discriminate against the recombination background, the elemental composition of the sample can be determined via the spectrally and temporally resolved detection of the characteristic atomic and ionic emissions. Due to the minimum sample preparation, the low cost for a single measurement, and the potential for an extensive automation, LIPS is an attractive approach to process analysis. The objective of this work to extend the range of elements, which can be analyzed by LIBS, via observation of atomic emission in the VUV range. This permits not only a multielement analysis of metals, but also access to emission lines of metalloids such as S, P, N, O, C, and As. Two experimental set-ups for VUV-LIBS are presented: A set-up for bulk analysis based on conventional Czerny-Turner monochromator and a new echelle spectrograph for high spectral resolution (> 10 000) in the spectral range 150-300 nm. Applying an appropriate beam shaping (3micro focusing4), LIPS allows a fast spatially resolved elemental characterization of surfaces with a typical resolution of 10 mm. Using a UV laser beam (l = 266 nm) for plasma ignition, fractionization effects can be minimized and a quantitative analysis can be performed. Analysis of the spectra from the single pulses permit a depth- and spatially resolved investigation of a sample.

Book excerpt: Laser-Induced Breakdown Spectroscopy (LIBS) is an analytical technique that has the potential to detect all the elements present in the periodic table. The limit of detection can go below a few ppm and this regardless of the physical phase of the analyzed sample (solid, liquid or gas). Its simplicity of use, its rapidity to get results and its versatility provide this technique with attractive features. The technique is currently developed for applications in a large number of domains such as online control, spatial explorations and the environment. However the weakness of the LIBS technique, compared to other more conventional ones, is still its difficulty in providing reliable quantitative results, especially for inhomogeneous and complex matrix such as organic or biological materials. The work presented in this thesis includes a study of the properties of plasma induced from different organic materials. First, a study of the plasma induced on the surface of a Nylon sample at short time delays (~ns) was carried out using the time-resolved shadowgraph technique for different experimental parameters (laser energy, pulse duration, wavelength). Then, a complete diagnostics of the plasma was performed using the plasma emission spectroscopy. A detailed analysis of the emission spectra at different detection delays allowed us to determine the evolution of the temperatures of the different species in the plasma (atoms, ions and molecules). The homogeneity and the local thermodynamic equilibrium within the plasma was then experimentally checked and validated. We demonstrated that the optimisation of the signalto- noise ratio and a quantitative procedure, such as the calibration-free LIBS, can be put in place within a properly chosen detection window. In our experiments, such optimised detection configuration was further employed to record LIBS spectra from different families of polymer in order to identify and classify them. For this purpose, the chemometrics procedure of artificial neural networks (ANN) was used to process the recorded LIBS spectroscopic data. The promising results obtained in this thesis makes LIBS stand out as a potentially useful tool for real time identification of plastic materials. Finally, this work can also be considered as a base for the further studies of more complex materials such as biological tissues with LIBS.
