研究岩石矿物包裹体和结晶中的水份及微量气体(又称挥发份),对了解岩石、矿床成因,划分成岩、成矿阶段,地球化学找矿,圈定矿区,计算储量及确定地质同位素年龄等,都有十分重要的意义。这种研究常常需要进行微量分析,这是一般分析方法很难做到的。气相色谱法由于具有很高的灵敏度和分离效能,样品用 Study of rock mineral inclusions and crystallization of water and trace gases (also known as volatile), to understand the rock, deposit genesis, divided into diagenesis, metallogenic stage, geochemical prospecting, delineation of mining area, calculate reserves and determine the geological isotope age Etc., have very important meanings. This kind of research often requires microanalysis, which is difficult to do with typical analytical methods. Gas Chromatography Due to its high sensitivity and separation efficiency, samples are used
