Název v původním jazyce

Laser induced breakdown spectroscopy in analysis of molten metals

Popis výsledku v původním jazyce

Laser-induced breakdown spectroscopy (LIBS) exploits laser ablation for spectrochemical analysis. During interaction of focused laser beam with a sample the microplasma is produced. The emission from the plasma is collected and monochromator disperses the radiation emitted by excited atoms and ions in the plasma. This radiation has analytical information and can be used for qualitative and quantitative purpose. Although main applications of LIBS techniques are focused on analysis of solid samples some works are devoted to analysis of liquid sample. Experimental set-up for LIBS analysis of molten metals was developed. Laser ablation parameters (laser beam energy, laser beam focusing) were optimized. Under this parameters influence of sample temperatureon LIP emission was studied. Nd:YAG laser (Quantel Brilliant, France) operated at wavelength of 1064 nm was used to produce microplasma on molten metal surface.
