近年来,色谱-质谱联用(以下简称色-质谱)技术迅速发展,在有机化学、生物化学、医药学、香料化学、农药、环境化学以及地球宇宙化学等领域中已得到了广泛的应用。色-质谱克服了过去气相色谱法在缺乏纯物质校对时难于定性的缺点和质谱方法对混合物中多组分共存时分析谱图的困难。所以色谱与质谱联用后兼备了色谱分离的特长和质谱鉴定灵敏的优点。因此在分析复杂混合物时显示了极大的优越性。在有机分析化学领域中已被公认为最有效的分析工具之一。根据毛主席关于“独立自主,自力更生,艰苦奋斗,勤俭建国”的方针和“洋
In recent years, the rapid development of chromatography - mass spectrometry (hereinafter referred to as color - mass spectrometry) technology, has been widely used in organic chemistry, biochemistry, medicine, perfume chemistry, pesticides, environmental chemistry and the earth’s chemistry. Chromatography - mass spectrometry overcomes the shortcomings of past gas chromatography, which are difficult to characterize in the absence of proofreading of pure substances, and the difficulties of mass spectrometry in analyzing spectra when multiple components coexist in mixtures. Therefore, both chromatographic and mass spectrometry combined with the advantages of chromatographic separation and mass spectrometry identification of the advantages. Therefore, the analysis of complex mixtures showed great superiority. It has been recognized as one of the most effective analytical tools in the field of organic analytical chemistry.
