Application of Laser-Induced Breakdown Spectroscopy for high-resolution elemental mapping

Popis výsledku v původním jazyce

Laser-Induced Breakdown Spectroscopy (LIBS) is an analytical technique based on spectroscopic analysis of radiation, which is emitted by a micro-plasma induced on the analyte surface by a laser pulse. In comparison to another advanced analytical techniques LIBS has several advantages. It allows analysis of samples in any state of matter practically in real-time and in-situ, without or with a limited sample preparation. It can be used for chemical mapping or chemical imaging of solid samples, i.e. it canprovide the information about the surface distribution of the individual chemical elements in the analyzed area in a very clear visual form. With certain limitations, the resulting chemical map may contain spectroscopic trace of all chemical elements present in the sample. The spatial resolution can go down to tens or even units of microns with limit of detection usually in tens to hundreds of ppm. Another advantage of LIBS is that it allows depth-profiling.
