    • A method is disclosed of identifying parent ions by matching daughter ions found to be produced at substantially the same time that the parent ions elute from a mixture. Ions emitted from an ion source (1) are transmitted to a fragmentation device (4) comprising an Electron Capture Dissociation, an Electron Transfer Dissociation or a Surface Induced Dissociation fragmentation device. The fragmentation device (4) is alternately and repeatedly switched between a first mode wherein the ions are substantially fragmented to produce daughter ions and a second mode wherein the ions are not substantially fragmented. Mass spectra are taken in both modes. At the end of an experimental run parent and daughter ions are recognised by comparing the mass spectra obtained in the two different modes. Daughter ions are matched to particular parent ions on the basis of the closeness of fit of their elution times, and this enables parent ions then to be identified.
    • 公开了一种通过匹配发现在母体离子从混合物中洗脱出的基本上同时产生的子离子来鉴定亲本离子的方法。 从离子源(1)发射的离子被传输到包括电子俘获解离,电子转移解离或表面诱导解离破碎装置的断裂装置(4)。 碎片装置(4)在其中离子基本上分裂以产生子离子的第一模式和第二模式之间交替地和重复地切换,其中离子基本上不分散。 质谱采用两种模式。 在实验运行结束时,通过比较两种不同模式中获得的质谱来识别母体和子离子。 基于其洗脱时间的拟合程度,子离子与特定的母体离子相匹配,这使得母体离子可以被鉴别。

    • A mass spectrometer is disclosed comprising a High Pressure Liquid Chromatography system (10) which is interfaced to a combustion chamber (16) and isotope ratio mass analyser (19) by means of an Electrospray Ionisation ion source (11) and a Field Asymmetric Ion Mobility Spectrometry device (13). Analyte and solvent molecules are ionised by the ion source (11). Desired analyte ions are substantially onwardly transmitted by the Field Asymmetric Ion Mobility Spectrometry device (13) to the combustion chamber (16) whereas undesired solvent ions are substantially attenuated by the Field Asymmetric Ion Mobility Spectrometry device (13).

    • A mass spectrometer is disclosed comprising a vortex mass filter/analyser. The vortex mass filter/analyser preferably comprises a chamber with a central rotatable shaft connected to a pressure reducing means. As the shaft rotates, a vortex is created within the chamber. The centrifugal force on an ion in the vortex is arranged to be balanced at a certain radius of rotation within the chamber by the electric force due to an opposed radial electric field. Ions having a certain mass to charge ratio are arranged to be maintained at a stable equilibrium at this radius and can then be selectively removed for further analysis. With this arrangement, no magnetic field is required and the apparatus can operate at pressures around that of atmospheric pressure.
    • 公开了一种质谱仪,其包括涡流质量过滤器/分析器。 涡流质量过滤器/分析器优选地包括具有连接到减压装置的中心可旋转轴的腔室。 当轴旋转时,在室内产生涡流。 涡流中的离子上的离心力被布置成由于相对的径向电场而由电力在室内的一定旋转平衡。 具有一定质荷比的离子被布置成在该半径处保持在稳定的平衡,然后可以选择性地去除以进一步分析。 通过这种布置,不需要磁场,并且该装置可以在大气压力附近的压力下工作。
