A magnetically rotating electric arc of coaxial design was produced in argon with and without zinc at 1 atm. The arc was characterized in terms of temperature by varying the source conditions. The axial temperatures decreased with distance from the cathode tip and the distribution was mathematically described by T = m * log (x) + b. The radial temperature distribution between the cathode and anode was determined by spectral analysis. The most homogeneous conditions with an argon/zinc plasma varied by approximately 4 % and could be applied in spectrochemical analysis. A steady state condition in terms of the frequency of rotation and gas and plasma temperatures was observed under all conditions with time. Equilibrium concentrations of species calculated with the computer program SOLGAS were found to be useful in predicting prevailing chemical conditions for a wide range of temperatures.
