众所周知,分析混合物时,首先需要把混合物中的各成分分离,然后才能够进行定性定量测定,这就使混合物的分析工作变得很复杂,有时甚至难以进行。自从色谱—质谱(GC/MS和LC/MS)联机分析仪器出现后,混合物分析获得迅速发展。但是,由于这两种仪器的操作性质截然不同,因此需要用一个特殊的接口装置把两个仪器联接起来,经过色谱和质谱
It is well known that when analyzing a mixture, it is first necessary to separate the components of the mixture before it can be qualitatively and quantitatively determined, which makes the analysis of the mixture complicated and sometimes difficult to perform. Since the advent of chromatographic-mass spectrometry (GC / MS and LC / MS) on-line analytical instruments, the analysis of mixtures has been rapidly evolving. However, due to the very different nature of the operation of these two instruments, a special interface device is required to link the two instruments through chromatographic and mass spectrometry
