中文摘要:
      光谱光源是光谱仪器和光谱技术的核心,等离子体光源是原子发射光谱技术的活跃领域之一,电感耦合等离子体(ICP)已成功地应用于原子发射光谱和无机质谱仪器。由于ICP光源采用氩气作为工作气体,耗量较大,降低氩气用量成为近些年来原子光谱技术研究和改进的重要目标。为此目的,已研究过各种低耗氩ICP光源,非氩气ICP光源,微波等离子体光源,射频电容耦合等离子体光源等。综述了近年这些等离子体发射光源的结构,分析性能及特点,以及它们所用工作气体情况。并归纳总结出,评价各种等离子体发射光谱光源应包括:等离子体温度(激发温度,气体温度),电子密度,工作气体种类及用量,元素检出限,光源的稳健性及经济方面等。
英文摘要:
      The spectral light source is the center of spectral instrument and spectral technology,the plasma light source is one of the active fields of atomic emission spectroscopy technology, inductively coupled plasma(ICP) light source has been successfully applied to atomic emission spectrometry and inorganic mass spectrometry. Becauseuseargon as working gas at Ar-ICP source and the argonconsumption is larger, so reduce the dosage of argon become the important goals ofresearch and improvement of the atomic spectrum technology in recent years.For this purpose, a variety of spectral light sources werestudied,included the argon ICP source of various low argon ICP source, the microwave plasma source (MIP,MPT) and radio frequency (rf) capacitively coupled plasma source(CCP) etc. In this paper, the structures, properties and characteristics of these plasma emission light sources werereviewed. It is also togeneralize andsummarizethat the evaluation of various plasma emission spectral light sources should includethe plasma temperature (excitation temperature Texc, gas temperature Tg), electron density, the type of working gas and amounts of gas, detection limits of elements, robustness of light sourcesand economical aspects etc.
