Book Description
The main result of our efforts is the development and successful application of the theoretical model of laser induced plasma (LIP) that allows a back-calculation of the composition of the plasma (and the condensed phase) based on the observable plasma spectrum. The model has an immediate experimental input in the form of LIP spectra and a few other experimentally determined parameters. The model is also sufficiently simple and, therefore, practical. It is conveniently interfaced in a graphical user-friendly form for using by students and any laboratory personnel with only minimal training. In our view, the model opens up the possibility for absolute analysis, i.e. the analysis which requires no standards and tedious calibration. The other parts of this proposal (including plasma diagnostics) were somewhat subordinate to this main goal. Plasma diagnostics provided the model with the necessary experimental input and led to better understanding of plasma processes. Another fruitful direction we pursued was the use of the correlation analysis for material identification and plasma diagnostics. Through a number of computer simulations we achieved a clear understanding of how, where and why this approach works being applied to emission spectra from a laser plasma. This understanding will certainly improve the quality of forensic and industrial analyses where fast and reliable material identification and sorting are required.

Laser-Induced Breakdown Spectroscopy
Author: Jagdish P. Singh
Publisher: Elsevier
ISBN: 0080551017
Category : Science
Languages : en
Pages : 455
Book Description
Laser induced breakdown spectroscopy (LIBS) is basically an emission spectroscopy technique where atoms and ions are primarily formed in their excited states as a result of interaction between a tightly focused laser beam and the material sample. The interaction between matter and high-density photons generates a plasma plume, which evolves with time and may eventually acquire thermodynamic equilibrium. One of the important features of this technique is that 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, leaf or blood) can be studied with almost equal ease. 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. The present book has been written by active specialists in this field, it includes the basic principles, the latest developments in instrumentation and the applications of LIBS . It will be useful to analytical chemists and spectroscopists as an important source of information and also to graduate students and researchers engaged in the fields of combustion, environmental science, and planetary and space exploration.* Recent research work* Possible future applications* LIBS Principles

Laser-induced Breakdown Spectrometry
Author: Yong-Ill Lee
Publisher: Nova Publishers
ISBN: 9781560728399
Category : Science
Languages : en
Pages : 194
Book Description
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.

Book Description
Volatiles in the Martian Crust is a vital reference for future missions - including ESA's EXO Mars and NASA's Mars2020 rover - looking for evidence of life on Mars and the potential for habitability and human exploration of the Martian crust. Mars science is a rapidly evolving topic with new data returned from the planet on a daily basis. The book presents chapters written by well-established experts who currently focus on the topic, providing the reader with a fresh, up-to-date and accurate view. Organized into two main sections, the first half of the book focuses on the Martian meteorites and specific volatile elements. The second half of the book explores processes and locations on the crust, including what we have learned about volatile mobility in the Martian crust. Coverage includes data from orbiter and in situ rovers and landers, geochemical and geophysical modeling, and combined data from the SNC meteorites. - Presents information about the nature, relationship, and reactivity of chemical elements and compounds on Mars - Explores the potential habitability of Mars - Provides a comprehensive view of volatiles in the Martian crust from studies of actual samples as well as from the variety of landed missions, including the MER and Curiosity rovers - Delivers a vital reference for ongoing and future missions to Mars while synthesizing large data sets and research on volatiles in the Martian atmosphere - Concludes with an informative summary chapter that looks to future Mars missions and what might be learned
