一导言目前,原子发射光谱分析发展的主攻方向之一乃是:更有效地同时多元素分析。其关键课题有两个。一是能够在可见、紫外以至于真空紫外这样一个很宽的光谱波段范围里,同时检测到大量的光谱讯息的光学和电子学测光系统的设计;二是稳定而有效的激发光源的开发。本文就前一个问题进行讨论。迄今,带有照像感光板或光电倍增管的棱镜或衍射光栅的色散系统是光谱信息测量主要技术。这种类型的仪器有摄谱仪、单色仪和光电直读光谱仪, 这些仪器装置都有各自独特优点,如光谱讯息量大,选线灵活,和可进行多元素同时测定等,因此在分析方面,仍然是重要的手段。但是,另一方面它们
I. INTRODUCTION At present, one of the main directions of the development of atomic emission spectrometry is to analyze multi-element elements more effectively simultaneously. There are two key issues. The first is the design of optical and electronic metering systems capable of detecting a large amount of spectral information over a wide spectral band of wavelengths such as visible, ultraviolet and vacuum ultraviolet. The second is the development of a stable and efficient excitation light source. This article discusses the previous question. Hitherto, the dispersion system of prisms or diffraction gratings with photographic plates or photomultipliers has been the main technique for measuring spectral information. This type of instrument spectrograph, monochromator and photoelectric direct reading spectrometer, these instruments have their own unique advantages, such as the amount of spectral information, flexible line selection, and can be multi-element simultaneous determination, so in the analysis Aspects remain an important means. But on the other hand they are
