气相色谱柱在石油、化工、生物化学、医药卫生、食品工业、环保等方面应用很广。它除用于定量和定性分析外，还能测定样品在固定相上的分配系数、活度系数、分子量和比表面积等物理化学常数。一种对混合气体中各组成分进行分析检测的仪器。工作原理色谱柱利用色谱柱先将混合物分离，然后利用检测器依次检测已分离出来的组分。色谱柱的直径为数毫米，其中填充有固体吸附剂或液体溶剂，所填充的吸附剂或溶剂称为固定相。与固定相相对应的还有一个流动相。流动相是一种与样品和固定相都不发生反应的气体，一般为氮或氢气。 待分析的样品在色谱柱顶端注入流动相，流动相带着样品进入色谱柱，故流动相又称为载气。载气在分析过程中是连续地以一定流速流过色谱柱的 而样品则只是一次一次地注入，每注入一次得到一次分析结果。 样品在色谱柱中得以分离是基于热力学性质的差异。固定相与样品中的各组分具有不同的亲合力(对气固色谱仪是吸附力不同，对气液分配色谱仪是溶解度不同)。当载气带着样品连续地通过色谱柱时，亲合力大的组分在色谱柱中移动速度慢，因为亲合力大意味着固定相拉住它的力量大。亲合力小的则移动快。检测器对每个组分所给出的信号，在记录仪上表现为一个个的峰，称为色谱峰。色谱峰上的极大值是定性分析的依据，而色谱峰所包罗的面积则取决于对应组分的含量，故峰面积是定量分析的依据。一个混合物样品注入后，由记录仪记录得到的曲线，称为色谱图。分析色谱图就可以得到定性分析和定量分析结果。
