质谱分析是通过将待测样品离子化再测定各组分离子的质荷比来进行分析的一种技术.自从1912年J.J.Thomson制成第一台质谱仪,100多年来科学家们不断探索、改善仪器性能,拓宽了质谱分析的应用领域.早期的质谱分析主要应用于同位素测定和无机元素分析,20世纪40年代以后初步应用于有机物分析.20世纪60年代出现的气相色谱-质谱联用以及70年代出现的液相色谱-质谱联用分析,使质谱检测的性能快速提升,应
Mass spectrometry is a technique for analyzing samples by ionizing and then determining the mass-to-charge ratio of each component ion. Since JJ Thomson made the first mass spectrometer in 1912, over 100 years scientists have been constantly exploring and improving Instrument performance, broaden the field of application of mass spectrometry analysis of early mass spectrometry is mainly used in isotope determination and inorganic elemental analysis, the 1940s after the initial application of organic matter analysis.20 gas generation of the 1960s appeared in combination with mass spectrometry and 70 The emergence of the liquid chromatography - mass spectrometry analysis, so that the rapid detection of mass spectrometry performance should be
