Spectrochemical Analysis with Time-Resolved Spark Spectra

Emission Characteristics and Sensitivity in a High-Voltage Spark Discharge.

“…Majkowski and Joseph (27) have studied the effects of excitation atmosphere on line-to-background intensity ratios obtained in a timeresolved spark, again without discriminating between various regions in the gap or offering specific mechanisms responsible for their observations. Steinhaus, Crosswhite, and Dieke (34) and Bardocz (3,4,8) have suggested that the simple isolation in time of background from line emission should increase sensitivity, mainly without discussing why and when background and line emission exist in different time domains. The possibility that the very act of introducing electrode material into the spark gap could produce heavy background has not been used to advantage.…”

Characterization of a copper spark discharge plasma in argon atmosphere used for nanoparticle generation

“…For example, great efforts were made as early as in the middle of the 20th century towards the description of processes taking place in analytical spark discharges (e.g. [23][24][25][26]). The following four stages are generally distinguished during the evolution of a high-voltage spark discharge: (i) pre-breakdown, (ii) breakdown, (iii) arc, and (iv) afterglow [26,27].…”

Nonferrous Metallurgy

“…Bardócz and Varsányl analyzed platinum alloys containing 1 to 25% rhodium using a solution technique (19). Carbon electrodes in a spoke arrangement on a slowly rotating shaft were dipped into the solution to be analyzed, after which they passed before a counter electrode.…”
