惰气熔融-红外吸收/热导法在无机固态材料气体分析中的应用

Application of inert gas fusion-infrared absorption or thermal conductivity method for gas analysis in inorganic solid materials

综述了近十年来惰气熔融-红外吸收/热导法在金属合金、稀土材料、冶金添加剂、耐火陶瓷等无机固态材料气体元素分析中的应用现状,侧重汇总了称样量、助熔剂、分析功率、标准样品等主要分析条件,介绍了氢、氧、氮元素分量测定的最新进展。讨论了该法存在的问题,并提出相关建议,展望了无机固态材料中气体分析的应用前景和发展方向。

The application status for gas analysis of inorganic solid materials,including metal alloys,rare earth materials,metallurgical additives and refractory ceramic,was reviewed by inert gas fusioninfrared absorption or thermal conductivity method.The main analytical conditions,such as sample mass,flux,analytical power and certified reference materials,were specially summarized,and the latest progress on the determination of partial hydrogen,oxygen and nitrogen was introduced.At last,the demerits of these two methods were discussed,and the related suggestions were proposed.Simultaneously,the application prospect and development of gas analysis in inorganic solid materials were forecasted.
