Application of Laser-induced breakdown
spectrometry for analysis of environmental and industrial materials
Abstract
Actual state of affairs,
main advantages and problems of Laser-Induced Breakdown Spectroscopy (LIBS) in
analysis of industrial materials and environmental samples are discussed.
Methods for LIBS sensitivity enhancement such as double-pulse ablation, a
combination of LIBS with laser-induced fluorescence, the use of additional
sources of excitation (spark) and confinement of plasma by magnetic field or
shock wave are compared with respect to figures-of-merit. A set of LIBS
approach to qualitative fast classification of materials, especially based on
the correlation between parameters of laser plasma and sample properties, are
discussed in details. Progress in environmental analysis of soils, sands etc.
with the use of LIBS is demonstrated. Detection limits of the most elements in
soils and aluminum alloys obtained until now are critically considered.
