    • The present application uses controlled fragmentation of parent molecular ions inside a mass spectrometer to determine aromatic cores or building block distribution of a petroleum resid. Various soft ionization methods, such as atmosphere pressure photoionization (APPI), atmospheric pressure chemical ionization (APCI), electrospray ionization (ESI), and MALDI etc. are used to generate molecular ions or pseudo -molecular ions. Ultra high resolution mass spectrometry by FTICR-MS provides elemental formulae of all ions. Parent ions are then fragmented inside the mass spectrometer to generate building block information using especially collision induced association (CID). The location of the fragmentation can be in a quadropole trap before the ICR cell or inside the ICR cell. By controlling the collision energy, fragementation can be restricted to only aliphatic bonds. So aromatic structures can be assigned to the fragments. In particular, by monitoring changes in the degree of unsaturation (Z -number or DBE) on fragmentation, it becomes possible to distinguish between single and multi-core species. Thus building block distributions can be determined by the technique and the composition of the resid generated from these building blocks.
    • 本申请使用质谱仪内的母体分子离子的受控碎裂来确定石油渣的芳香核心或构建块分布。 使用大气压光电离(APPI),大气压化学电离(APCI),电喷雾电离(ESI)和MALDI等各种软电离方法产生分子离子或假分子离子。 通过FTICR-MS的超高分辨率质谱法提供所有离子的元素配方。 然后,母体离子在质谱仪内分裂,以产生使用特别是碰撞诱导缔合(CID)的构建块信息。 碎片的位置可以在ICR细胞之前或ICR细胞内的四极陷阱中。 通过控制碰撞能量,分裂可以仅限于脂肪键。 所以芳香结构可以分配给片段。 特别地,通过监测不稳定度(Z-数或DBE)在分段上的变化,可以区分单核和多核物种。 因此,构建块分布可以通过从这些构建块生成的技术和残差的组成来确定。

    • 本申请使用质谱仪内的母体分子离子的受控碎裂来确定芳族核心或石油渣油的积木分布。 使用各种软电离方法,例如大气压光电离(APPI),大气压化学电离(APCI),电喷雾电离(ESI)和MALDI等来产生分子离子或假分子离子。 FTICR-MS的超高分辨率质谱提供了所有离子的元素分子式。 然后,母离子在质谱仪内部碎裂以使用特别是碰撞诱导的关联(CID)生成构件块信息。 碎片的位置可以位于ICR单元之前或ICR单元内的四极捕获器中。 通过控制碰撞能量,裂纹可以仅限于脂肪键。 因此可以将芳香族结构分配给碎片。 特别是,通过监测碎裂中不饱和度(Z-数量或DBE)的变化,可以区分单核物种和多核物种。 因此,积木分布可以通过由这些积木产生的渣油的技术和组成来确定。
