| Abstract: | Higher concentrations of non-easily ionized elements (NEIE) increase the spectral line intensity of trace elements in the arc plasma. It was found that these additives do not greatly affect the evaporation processes of the trace elements. Changes in temperature, electron density and transport velocities together can optimize the excitation for particular atomic species. The importance of the investigations is to underline the possible application of NEIE in spectrochemical practice. |
