随着科学技术和工业的高速发展,可见紫外的光谱分析的现有方法已经远远不能适应形势的需要:第一:由于使用电弧、火花光源,激发能量太低,灵敏度和重现性都受到很大的限制,况且,每次分析必须研制标样,绘制工作直线,分析程序费时繁琐。第二:气体、非金属元素的最灵敏线大部份都不在可见紫外区域。尤其是气体元素,具有相差很大的电离电位和激发电
With the rapid development of science and technology and industry, the existing methods of visible ultraviolet spectrum analysis are far from being able to meet the needs of the situation. First, due to the use of arcs and spark sources, the excitation energy is too low, the sensitivity and reproducibility are affected Great limitations, Moreover, each analysis must develop standard samples, drawing a straight line, the analysis process time-consuming and cumbersome. Second: most of the most sensitive lines of gas, non-metallic elements are not in the visible ultraviolet region. In particular, the gas element has a very different ionization potential and excitation power
