摘要

质谱仪可以提供有关分子组成和化学结构的信息。然而,在复杂的混合物中,可能会出现信号的叠加甚至抑制。另一方面,色谱法是分离配合物的理想技术,但往往不足以用于化合物鉴定。因此,将这两种技术结合起来以消除每种技术的局限性是非常有意义的。在这篇文章中,将简要介绍气相和液相中质谱法与色谱法的耦合,以解释耦合这两种方法的优点。对离子化技术进行了报道,并介绍了离子化技术的应用领域。最后,对实验结果的记录和处理进行了综述。

Mass Spectrometry Coupled with Chromatography toward Separation and Identification of Organic Mixtures
Mass spectrometers can provide information about molecular composition and chemical structure. However, with complex mixtures, superpositions and even suppression of signals may occur. On the other hand, Chromatography is an ideal technique for separating complexes but is often insufficient for compound identification. Hence, coupling both techniques in order to eliminate the limitations of each technique makes perfect sense. In this contribution, a brief description of mass spectrometry coupled with chromatography in the gas and liquid phase will be discussed to explain the advantages of coupling the two methods. The ionization techniques are also reported and followed by application areas of these techniques. Finally, the recording and treatment of the results are reviewed.
