| 摘 要： | 离子阱检测器的原理不同于四极杆和磁质谱仪。采用ＩＮＣＯＴＭ库检索和概率匹配（ＰＢＭ）算法，把五百余种环境中常见有机化合物的离子阱质谱与国际上通用的ＮＢＳ质谱库及Ｗｉｌｅｙ质谱库中质谱数据相比，其结果是绝大部分化合物的离子阱质谱与经典质谱非常相似，极少数化合物的质谱二者之间存在某些差异，文中分析了可能导致差异的原因。

| Abstract: | The principle of ion Trap Detector (ITD) is different from that of quadrupole and magnetic mass spectrometers. Using INCOSTM library search and probabitity based matching algorithm, by comparison of ITD spectra with NBS and Wiley spectra for more than 500 organic compounds which appear as enviromental pollutants, it is found that spectra are similar for majority of them, and different to various extents for others.Possible causes of the spectral differences are discussed. |
