Abstract The effect of current strength, pre-batching time, frequency and duration of a discharge pulse, as well as the operational parameters of a two-jet arc plasma (TJP) torch (angle between plasma jets, gas flow) on the value of the analytical signal and standard deviation are studied. The influence of the operational parameters of spark ablation on the morphology and particle size of the resulting aerosol was studied. The optimal conditions for the analysis of steels by the method of TJP-OES with spark ablation were selected. The analytical capabilities of the method are evaluated in the analysis of steels. The limits of detection (LODs) for Cr, Cu, Mn, Mo, Ni, Si, and V during TJP-OES analysis of steels with spark ablation are in the range of n·10−5 ÷ n·10−3% wt.
