Book excerpt: ABSTRACT: Since its early applications, Laser-Induced Breakdown Spectroscopy (LIBS) has been recognized as a useful tool for solid state chemical analysis due to its numerous attractive advantages as an analytical tool: e.g., simultaneous multi-element detection capability, no sample preparation, rapid or real-time analysis, and allowing in situ analysis requiring only optical access to the sample. However, the quantitative accuracy of the technique depends on the complex fundamental processes involved in laser-induced plasma formation, ablation, atomization, excitation and ion recombination. Thus, problems arising from laser target coupling, matrix effects, line interferences, fractionation in target vaporization, the main assumptions of the methods, namely the optically thin emission of spectral lines and the existence of local thermodynamic equilibrium in the plasma should be properly addressed in order to obtain reliable quantitative results [1, 2] . The general scope of this research encompasses two aspects related to the LIBS technique: one aspect is the fundamental study of the plasma characteristics and another is an improved use of the technique in quantitative analysis. The main project is to revisit and investigate some fundamental assumptions such as the existence of local.

Book Synopsis Laser-induced Breakdown Spectrometry by : Yong-Ill Lee

Download or read book Laser-induced Breakdown Spectrometry written by Yong-Ill Lee. This book was released on 2000. Available in PDF, EPUB and Kindle. Book excerpt: When the output from a pulsed laser is forced onto a small spot of a sample, optically induced plasma, called laser-induced plasma (LIP) is formed at the surface. The plasma is formed when the laser power density exceeds the breakdown threshold value of the surface. The plasma can be used in sampling but is proposed as a source for atomic emission spectrometry (AES). In this case the technique is referred to as laser induced breakdown (emission) spectrometry (LIBS). The spectrally and temporally resolved detection and subsequent determination of the specific atomic emission reveals analytical information about the elemental composition of the sample, including solids, liquids and gases. This book is devoted to the analytical technique of laser-induced breakdown spectrometry. An introduction covering some basic principles of atomic emission spectrometry, analytical performance characteristics, and a comparison to more conventional techniques provides background information for the reader. The book is then conveniently divided into three parts: the first part described the instrumentation required and options available, the second part on fundamental studies of the laser plasma, and the third part on applications. Finally the future development of LIBS is presented.
