气体色层法是近十年来新发展起来的一种新的色层方法。这种方法,不仅具有灵敏、快速及操作简便等优点,而且只需极小量的样品即能进行混合物的分离、鉴定和获得准确的定量结果。色层法的原理系基于样品组分在固定相中的吸附或在不相容和的两相(液体固定相和液体流动相)中分配的不同而获得分离。应用流动气体代替通常的液体流动和的色层分析方法 Gas chromatography is a new color method newly developed in recent ten years. This method not only has the advantages of sensitivity, quickness and easy operation, but also separates, identifies and obtains accurate quantitative results with only a very small amount of sample. The principle of chromatographic separation is based on the adsorption of the sample components in the stationary phase or the partitioning in the incompatible and the two phases (liquid stationary phase and liquid mobile phase). Application of mobile gas instead of the usual liquid flow and chromatographic analysis
