利用互补离子迁移率/质谱仪(IM/MS)和超高分辨率傅立叶变换离子回旋共振(FTICR)MS对轻、中、重质原油进行了分析，得到了含杂原子的碳氢化合物的分布以及多个构象类。IM/MS技术为快速识别特征构象/组成模式提供了独特的指纹，而FTICR MS分析提供了全面的杂原子类别分布。IM/MS和FTICR MS结果表明，从轻质原油到中质原油再到重质原油的组成复杂性增加。对迁移率结果的考察表明，CnHhXY(XY=N-1、S-1、N-1、O-1、NS、SO1-2、NO1-2等)具有较高的结构多样性。随着质量的增加，从平面结构向更紧凑的三维结构的转变。
Here, complementary ion mobility/mass spectrometry (IM/MS) and ultrahigh-resolution Fourier transform ion cyclotron resonance (FTICR) MS analyses of light, medium, and heavy petroleum crude oils yielded distributions of the heteroatom-containing hydrocarbons, as well as multiple conformational classes. The IM/MS technique provides unique fingerprints for fast identification of signature conformational/compositional patterns, whereas FTICR MS analysis provides comprehensive heteroatom class distributions. IM/MS and FTICR MS results reveal an increase in compositional complexity in proceeding from light to medium to heavy crude oils. Inspection of the mobility results shows a high structural diversity for the CnHhXY (XY = N-1, S-1, N-1, O-1, NS, SO1-2, NO1-2, etc.) series, as well as a shift from planar to more compact three-dimensional structures with increasing mass.
