气液色谱法是发展中的分析方法之一,由于它具有很高的选择分离效能,从而为复杂组分的鉴定创造了先决条件。气液色谱分离中起主导作用是色谱柱,除了毛细管或空心柱外,一般填充柱皆是以液相均匀地涂渍在多孔“惰性”担体上形成液膜而起分配作用的。担体的特性主要决定于二个因素(1)担体结构:指担体的孔径大小、孔径分布、孔隙率及由此而决定的比表面积等;(2)担体的表面
Gas-liquid chromatography is one of the developing analytical methods, which has created the preconditions for the identification of complex components due to its high selective separation efficiency. Gas chromatographic separation plays a leading role in the chromatographic column, in addition to the capillary or hollow column, the general column are filled with liquid evenly coated on porous “inert” body to form a liquid film and distribution. The characteristics of the carrier are mainly determined by two factors: (1) the structure of the carrier: the size of the carrier, the pore size distribution, the porosity and the specific surface area determined therefrom; (2) the surface of the carrier
