The capability of utilizing lasers as an excitation source for spectrometric microanalysis in different fields was recognized soon after the development of the first laser devices. Advanced laser-based techniques allow fast and accurate study of different materials both for analysis in the laboratory and industrial environments [1, 2]. For trace and ultra-trace analysis of solid samples the laser-ablation was coupled to Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES) or Inductively Coupled Plasma – Mass Spectrometry (ICP-MS) [3, 4]. More recently, Laser-Induced Breakdown Spectroscopy (LIBS) has been introduced. LIBS utilizes the high power densities obtained by focusing the radiation from a pulsed, and fixed frequency laser to generate in the focal region a luminous micro-plasma from an analyte (solid, liquid and gaseous samples). The micro-plasma emission is subsequently analyzed by spectrometer. In a good approximation, the plasma composition is representative to the analyte’s (en)
Společný vývoj bezkalibrační kvantitativní LIBS analýzy (CF-LIBS) vybraných vzorků. Aplikace postupu CF-LIBS nejenom v laboratorních podmínkách, ale i s využitím aparatury pro dálkovou LIBS (rLIBS).
The project contributed to further development of the analytical technique LIBS capable of qualitative and for selected elements also quantitative elemental real-time analysis with high spatial resolution in both laboratory and extralaboratory conditions. The results of the project were published in 3 papers and publicized in 25 presentations on international scientific conferences. (en)
Projekt přispěl k vývoji analytické metody LIBS, schopné kvalitativní a pro vybrané prvky i kvantitativní elementární analýzy v reálném čase s vysokým plošným a prostorovým rozlišením jak v laboratorních, tak i v mimolaboratorních podmínkách. Výsledky projektu byly publikovány v 3 článcích a 25 konferenčních příspěvcích. (cs)
