气相色谱(简称GC)对混合物是一种非常有效的分离手段,但是气和色谱得到的数据只是分离出来的各个成分的保留时间。因此要将分离出来的化合物作出明确鉴定是很困难的。质谱(简称MS)恰恰相反,它对混合物的分析是很困难的,而对纯化合物是一种高灵敏度的定性手段。气相色谱和质谱相互配合使用,即GC/Ms联用,则在中药分析上显示了巨大的威力。它能够在较短
Gas chromatography (abbreviated as GC) is a very effective separation method for the mixture, but the data obtained by gas and chromatography is only the retention time of the separated components. Therefore, it is very difficult to make a clear identification of the separated compounds. Mass spectrometry (abbreviated as MS) is just the opposite. It is very difficult to analyze the mixture and it is a highly sensitive qualitative method for pure compounds. Gas chromatography and mass spectrometry used in conjunction with each other, that is, GC/Ms, showed great power in the analysis of traditional Chinese medicine. It can be shorter
