便携式原子吸收光谱仪的研究与探讨

摘要

The current state of research and development on portable atomic absorption spectrometers is described, with focuses on the design and performance testing of the key technical components:tungsten-coil atomizers, light sources, and CCD spectrometers; as well as on the analytical method of these instruments. The performances of portable atomic absorption spectrometers and that of conventional atomic absorption spectrometers on the detection of several typical test elements are compared, and the unique features of using the portable instruments as well as the development potential are also discussed.%介绍便携式原子吸收光谱仪的研究与探索过程,说明其关键技术:钨丝电热原子化系统和光源、CCD分光检测系统的结构、性能试验研究以及仪器分析方法.通过对便携式原子吸收光谱仪与常规原子吸收分光光度计的分析性能,以及比较典型元素的测试结果,探讨便携式仪器的分析特点和发展前景.
