质谱技术是一种具有高灵敏度、高鉴别力,能和其它分析分离技术(超临界色谱、气相色谱质谱等)相互兼容的分析技术。它是各种学科研究的重要技术手段,在近年来发展迅速,其被应用的领域不仅广泛,它使用的仪器种类也在不断改进、更新。其中的气相色谱法和气质联用技术在寻找挥发性有机物和痕量物质分析中的作用尤为突出。 MS technology is a high sensitivity, high discrimination, and other analytical separation techniques (supercritical, gas chromatography, etc.) compatible with the analytical techniques. It is an important technical means of various disciplines and has been developing rapidly in recent years. Its fields of application are not only extensive, but the types of instruments it uses are constantly improving and updating. Among them, GC and GC-MS are particularly effective in the analysis of volatile organic compounds and trace substances.
