本文介绍了自制Kranz式的直流等离子喷射焰发生器的装置、构造和工作原理;并研究了它的特性。利用直流等离子火焰作为发射光谱分析的光源,考虑了试样化学组份的影响,进行了合金中铝的测定。
This article introduces the device, structure and working principle of self-made Kranz-type DC plasma jet flame generator; and studies its characteristics. The direct current plasma flame was used as the light source for the emission spectrum analysis. The influence of the chemical composition of the sample was taken into account and the determination of aluminum in the alloy was carried out.
