将纯钽及纯钽制品完全转化成氧化物，按一定比例与载体混合，直流电弧阳极激发，梯光栅和棱镜色散系统进行分光，选择特征谱线由检测器进行信号接收，由计算机进行数据转换和处理。用直流电弧光谱法测定钽中钼元素，方法线性范围5~440 μg/g，并建立了作业指导流程，该法可完全满足生产过程分析工作的快速和准确度需求。
The pure tantalum and pure tantalum products are converted into oxides completely, and it was mixed with the carrier material in a certain proportion, and stimulated by the DC anode arc. The split light is developed by using the ladder grating and the prism dispersion system. The selected spectral line is received by the detector, and the data are converted and processed by a computer. The DC arc spectroscopy was used to determine the molybdenum element in tantalum, and the linear range of the method was 5 - 440 μg/g, and an operation instruction was established, this method can fully meet the needs of speed and accuracy during the production process analysis.
