The analytical capabilities of the atomic emission spectrometry method with a two-jet arc plasmatron (TJP-OES) using spark ablation are estimated. The influence of the frequency and duration of the discharge impulse, as well as the operating parameters of the plasma torch on the value of the analytical signal and standard deviation, has been studied. The dependences of the analytical signal on the duration of the spark discharge were obtained, and the optimal sparking time to obtain a stable signal has been found. The detection limits of Cr, Cu, Mn, Mo, Ni, Si, and V during the TJP-OES analysis of steel with spark ablation are in the range of n × 10−5 ÷ n × 10−3 wt%.

使用带火花烧蚀的双射弧等离子加速器通过原子发射光谱法进行钢分析
估算了使用火花消融的双射弧等离子加速器（TJP-OES）的原子发射光谱法的分析能力。研究了放电脉冲的频率和持续时间以及等离子炬的工作参数对分析信号值和标准偏差的影响。获得了分析信号对火花放电持续时间的依赖性，并且找到了获得稳定信号的最佳火花时间。在通过电火花烧蚀的TJP-OES分析过程中，Cr，Cu，Mn，Mo，Ni，Si和V的检测限在n ×10 -5 ÷ n ×10 -3 wt％的范围内。
