Abstract
Efficiency of the suggested tandem technique of Marinković burner was studied in terms of the influence of the PC-controlled DC arc of the different intensities (10 A, 15 A, 20 A, 25 A) on the evaporation process. Higher intensities than 25 A did not allow to use the given experimental equipment since they cause plasma instability and periodic plasma quenching. The suggested method was evaluated by the determination of the half (t 50%) and total (t 100%) evaporation time and by determination of the signal/background ratio for the chosen elements (Al, Ca, Cr, Fe, Mg, Ni, Si, and V) in the model graphite matrix.
