Laser-Induced Breakdown Spectrometry in analysis of melts

Popis výsledku v původním jazyce

LIBS is a type of atomic emission spectroscopy which uses a focused highly energetic laser pulse as the excitation source. In principle, any physical state (solid, liquid or gas) can be analyzed by LIBS with low detection limits for most elements. The aim of this work was to construct a new compact experimental setup with unvarying optical path for analysis of melt by means of Laser-Induced Breakdown Spectrometry (LIBS) and to observe an influence of surrounding gas (air, He and Ar) on time resolved Laser-Induced Plasma (LIP) emission. The whole study was performed using glass samples. LIP was produced using Nd:YAG laser (Quantel, France) operated at fundamental wavelenght of 1064 nm and frequency 1 Hz. Laser beam was focused by quartz lens with focaldistance 100 mm. Radiation was transported into monochromator TRIAX 320 (Jobin Yvon, France) by optical cable. Monochromatic radiation was detected by the ICC detector (Jobin Yvon, France) for a record of emission spectrum.
