第二部分:气相色谱柱总的分离效能指标寻找高效能的色谱柱,是多年来气相色谱工作者的一个努力的方向。对于一个高效能的色谱柱来说,决定的因素有两个:一个是固定相的选择性;一个是操作变数对分离的影响。围繞着这些方面的工作很多。近年来,卢佩章发表了一系列的研究成果。提出用选择性指标H值和操作效能指标F值之乘积代表气相色谱柱的总的分离效能指 Part II: General Column Performance Indicators for Gas Chromatography Looking for high performance columns has been an area where gas chromatographers have worked for years. For a high-performance column, there are two determinants: one is the selectivity of the stationary phase and the other is the effect of manipulated variables on the separation. There is a lot of work around these areas. In recent years, Lu Peizhang published a series of research results. Proposed by the selective index H value and the value of the operating performance index F value on behalf of the GC column total separation efficiency
