چکیده
In the last few years, LIBS has become an established technique for assessment of elemental concentrations in various sample types. However, many applications knowledge about overall composition is not sufficient. addition, detailed information distribution within a heterogeneous needed. great interest imaging studies, since this allows to associate obtained with spatial coordinates investigated sample. The possibility simultaneous multi-elemental analysis major, minor, and trace constituents almost all types solid materials no or negligible preparation combined high speed are benefits which make especially attractive when compared other techniques. first part review aimed at providing instrumental requirements necessary successful measurements points out discusses state-of-the-art instrumentation upcoming developments. second dedicated data processing evaluation data. This chapter focused on different approaches multivariate chemometrics can be used e.g. classification but also quantification final part, current literature ranging from bioimaging, geoscientific cultural heritage studies field science summarized reviewed.

Quantitative elemental analysis by laser-induced breakdown spectroscopy
Laser-induced breakdown spectroscopy (LIBS) has been popular in elemental analysis for various kinds of samples due to its rapid and in-situ measurement using simple equipment. However, quantitative analysis by LIBS is still inferior to conventional element analysis methods in sensitivity and accuracy. In this paper improvement in LIBS is attempted applying computational processing to low-resol...
متن کاملLaser Induced Breakdown Spectroscopy
Laser-induced breakdown spectroscopy (LIBS) is a powerful analytical technique that can be used for the detection and characterization of materials. In LIBS, a focused laser beam is used to generate a plasma plume on the surface of solid and liquid samples or inside the sample volume of gases, liquids, and aerosols. Each excited atom in the plasma emits a unique set of spectral lines, particula...

متن کاملFemtosecond laser-induced breakdown spectroscopy: physics, applications, and perspectives.
Progress in technology and society continually places new demands on analytical science and more powerful and informative methods need to be developed. One among them is laser-induced breakdown spectroscopy (LIBS), sometimes also referred to as LIPS (laserinduced plasma spectroscopy). Typically, LIBS measurements are conducted with nanosecond time scale lasers. A review by Song et al.1 and two ...
