空心阴极光源在高分辨率光谱学及同位素分析中的应用,可以追溯到半个世纪以前,可是它在发射光谱分析中的应用,则是近二十年来的事。通过国内外许多光谱分析工作者的努力,空心阴极光源在难激发元素分析,难熔金属、难熔合金及难熔氧化物中微量元素分析,气体元素分析,特别是高纯物质分析等方面,已取得了显著的成效;有的已经列入日常分析方法,配合工业生产和科学研究。但是,这种新型光源没有象电弧、火花光源那样,在许多工厂和试验室得到广泛的应用。产生这种情况的主要原因是:国外空心阴极光源的常规设计比较复杂,需要昂贵、娇气
The application of hollow cathode light sources in high-resolution spectroscopy and isotope analysis dates back more than a half-century ago, but its use in emission spectroscopy has been in the past two decades. Through the efforts of many spectroscopic analysts both at home and abroad, hollow cathode light source has been widely used in refractory elemental analysis, refractory metals, refractory alloys and refractory oxides in trace elements analysis, gas elemental analysis, especially high purity material analysis, Has achieved remarkable results; some have been included in routine analysis methods, with industrial production and scientific research. However, this new type of light source is not as arc, spark light, as many factories and laboratories have been widely used. The main reason for this situation is: the conventional design of hollow cathode light sources abroad is more complex, expensive and delicate
