金属中气体分析现状与未来

综述了金属中气体分析概况, 提及元素周期表中所有气体元素以及碳和硫。提出常规气体分析已经从氧氮氢碳硫扩大至氦和氩。气体分析所涉及材料种类不断增加, 从金属及合金扩大至冶金炉料、金属氧化物和陶瓷材料等等。气体分析检测极限不断被刷新, 向着更低和更高方向发展。脉冲熔融-质谱新方法应用于金属中气体分析, 可做到氧氮氢氩4元素同时测定, 有可能助推改变气体分析现状。火花源原子发射光谱仪和X射线荧光光谱仪等其他非气体分析专业仪器也正交叉渗入。诸如, 二次离子质谱(SIMS), 离子探针(IM)和电子探针(EP)等微观分析手段一直作为金属中气体分析的辅助手段, 随着未来发展可能转变为主要手段。

The status quo and prospect of gas analysis in metal

This paper provides an overview on the gas analysis in metals with reference to all the gas elements in the periodic table as well as carbon and sulfur. It’s proposed that the conventional gas analysis has expanded from oxygen, nitrogen, hydrogen, carbon and sulfur to helium and argon. Gas analysis involves increasingly more types of materials, from metals and alloys to metallurgical furnace charges, metal oxides and ceramic materials, to name a few. The detection limit for gas analysis has been constantly renewed, toward both the lower and higher directions. New pulse heating-mass spectrometry have been applied to the gas analysis in metals and achieved simultaneous determination of four elements including oxygen, nitrogen, hydrogen and argon, so it is possible to boost changes in gas analysis. Spark source atomic emission spectrometer, X-ray fluorescence spectrometer and other non-special gas analysis instruments are also employed. For example, such means of microscopic analysis as secondary ion mass spectrometry (SIMS), ion probe (IM) and electron probe (EP) has been used as adjuncts in the gas analysis in metals, but they may grow into the major means as they develop.
