显像管石墨乳的综合分离分析方法介绍

Comprehensive Analytical Separation and Indentification Methods of Graphite Emulsions for Kinescopes

摘要: 利用薄膜渗析、溶剂萃取、液固柱色谱分离、薄层色谱分离、热裂解等分离方法和红外光谱、发射光谱、χ射线粉末衍射、元素分析、气相色谱、点滴试验等测试鉴定手段在对多种进口显像管石墨乳进行分离分析的基础上,建立了一套适合于各类像管石墨乳的分离分析鉴定方法.

Abstract: In this paper, We report a series of analytical separation methods e.g. distillation,dialysis,solvent extraction,liquid-solid chromatgraphy and thin layer chromatgraphy and infrared spectroscopy,emission spectroscopy,X-ray powder diffraction,gas chromatgraphy, element analysis,spot test etc.identification methods.By applying these approaches we had successfully analyzed many graphite emulsions for kinescopes.
