    • The invention relates to the identification of microbes in a sample by calculating the similarities between a mass spectrum of the sample and all reference spectra in a spectral library; it particularly concerns the detection of microbe mixtures. Microbe mixtures are probably present if several microbe species which are not closely related to each other are among the score list containing the most similar reference spectra. Methods are proposed which (1) operate with a list of the relationships, (2) determine the similarity between the reference spectra of the different microbe species of the score list, or (3) always carry out a mixture analysis in accordance with document DE 10 2009 007 266 Al from the score list, with the generation of combination spectra, and only afterwards check the similarity of the combined spectra and thus the relationship between the microbe strains concerned.

    • The invention relates to devices and methods for the acquisition of mass spectra with very high mass resolution in ion cyclotron resonance mass spectrometers and methods to produce the devices. The invention presents cylindrical ICR measuring cells with special electrode geometries to generate harmonic trapping potentials for orbiting ions up to the walls of the cell. Only a single DC trapping voltage has to be applied to create the harmonic trapping potential distribution. The sheath of the cylindrical cell is divided by longitudinal gaps into a multitude of sheath electrodes, which either have to carry layers with resistance profiles able to generate parabolic voltage profiles along the sheath electrodes, or which form sheath electrodes of varying width by parabolic gaps, able to create complicated potential distributions which are harmonic on average for orbiting ions. Orbiting ions of a given mass m/z can oscillate harmonically in axial direction with exactly the same oscillation frequency, independent of the radius of their orbit and of their axial osci llation amplitude. Ideally, the cylinders are closed by endcaps with rotationally hyperbolic form, divided into partial electrodes like in infinity cells. The ions can then be excited to their cyclotron motions by dipolar excitation fields also uniformly filling the ICR cell up to the endcaps. The ion clouds orbiting on their cyclotron trajectory are kept together for much longer periods than was possible hitherto, even if they orbit near the sheath electrodes. The image currents thus give rise to minute-long transients, from which mass spectra with ultrahigh mass resolution can be obtained.
    • 本发明涉及用于在离子回旋共振质谱仪中以非常高质量分辨率获取质谱的装置和方法以及用于生产该装置的方法。 本发明提出了具有特殊电极几何形状的圆柱形ICR测量单元,以产生用于将离子旋转至电池壁的谐波陷阱电位。 必须应用单个DC捕获电压来产生谐波捕获电位分布。 圆柱形电池的护套由纵向缝隙分成多个护套电极,这些护套电极必须携带具有能够沿着护套电极产生抛物线电压分布的电阻分布的层,或者通过抛物线间隙形成不同宽度的护套电极, 能够创建复杂的电位分布,它们是轨道离子的平均谐波。 给定质量m / z的轨道离子可以以完全相同的振荡频率在轴向上谐振振荡,与轨道的半径及其轴向振幅无关。 理想情况下,气瓶由具有旋转双曲形式的端盖封闭,分成如无限细胞中的部分电极。 然后可以通过偶极激发场将离子激发到它们的回旋加速器运动,同时也将ICR单元均匀地填充到端盖。 在其回旋加速器轨迹上运动的离子云保持在一段比迄今为止更长的时间段,即使它们在护套电极附近轨道运行。 因此,图像电流产生微小的瞬变,可以获得具有超高质量分辨率的质谱。

    • The invention relates to ions guided by gas flows in mass spectrometers, particularly in RF multipole systems, and to RF quadrupole mass filters and their operation with gas flows in tandem mass spectrometers. The invention provides a tandem mass spectrometer in which the RF quadrupole mass filter is operated at vacuum pressures in the medium vacuum pressure regime, utilizing a gas flow to drive the ions are through the mass filter. Vacuum pressures between 0.5 to 10 pascal are maintained in the mass filter. The mass filter may be enclosed by a narrow enclosure to guide the gas flow. The quadrupole mass filter may be followed by an RF multipole system, operated at the same vacuum pressure, serving as fragmentation cell to fragment the selected parent ions. The fragmentation cell may be enclosed by the same enclosure which already encloses the mass filter, so the ions may be driven by the same gas flow at the same vacuum pressure, greatly simplifying the required vacuum pumping system in tandem mass spectrometers. There are many other applications utilizing gas flows including supersonic gas jets in mass spectrometry.
    • 本发明涉及在质谱仪,特别是RF多极系统中的气流引导的离子,以及RF串联质谱仪和其在串联质谱仪中的气流的操作。 本发明提供一种串联质谱仪,其中RF四极杆质量过滤器在中等真空压力状态下在真空压力下操作,利用气流驱动离子通过质量过滤器。 在质量过滤器中保持0.5至10帕斯卡之间的真空压力。 质量过滤器可以被狭窄的外壳包围以引导气流。 四极质量过滤器之后可以是在相同的真空压力下操作的RF多极体系统,用作碎裂细胞以分离所选择的母体离子。 分裂单元可以被已经包围质量过滤器的相同外壳封闭,因此离子可以在相同的真空压力下由相同的气流驱动,大大简化了串联质谱仪中所需的真空泵送系统。 在质谱法中还有许多其他的应用,包括使用超声波气体射流的气流。

    • The invention relates to methods and instruments for the rapid detection and rapid mass spectrometric identification of microbial infective agents in blood or other body fluids. The invention recognizes that blood is not a good environment for the cultivation of microbes and provides a method which (a) largely destroys or dissolves the human particles in body fluids, such as erythrocytes and leukocytes in blood, without impairing the ability of the microbes to reproduce, (b) separates the microbial pathogens from the fluid, (c) cultivates them in a nutrient broth which contains none of the antimicrobial components of the body fluids, (d) separates them from the nutrient broth, and (e) identifies the microbes by a mass spectrum of the microbial proteins. The dissolution of the human particles also releases the microbes nesting in macrophages. The cultivation in an optically clear nutrient broth with optimum composition not only accelerates the propagation of the microbes compared to all other cultivation methods, but also makes it possible to continuously measure their quantitative growth starting from a low microbe density. This firstly allows the mass spectrometric identification to be carried out at the earliest possible time, secondly provides a positive detection of microbes far ahead of their identification, which can be lifesaving for the patient; and thirdly makes it possible to start the determination of resistances early.
