Název v původním jazyce

Normalization of LIBS spectra using acoustic and total emission signal

Popis výsledku v původním jazyce

Since that laser-induced plasma emission is extremely dependent on the initial conditions, significant fluctuations occur even with constant parameters and a strict control of the experimental setup. Laser-Induced Breakdown Spectroscopy (LIBS) signal intensity suffers from the specific influences resulting from the laser ablation and plasma processes which affect the accuracy and precision of analytical result. To improve reproducibility and accuracy utilization of alternative normalization procedure based on plasma monitoring is possible. In our study for careful correction of the pulse -to- pulse changes of sampling parameters acoustic and total emission were used. Correlation between total optical emission and acoustic signal is demonstrated and effect of the laser pulse energy, focusing and nature of sample is discussed. Normalization of LIBS spectra using acoustic and total emission signal in bulk analysis, depth profiling and surface mapping is presented.
