    • 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,通过比较在两种不同模式中获得的质谱来识别母体和子体离子。 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 method of mass spectrometry is disclosed wherein voltage signals from an ion detector are analysed. A second differential of each voltage signal is obtained and the start and end times of observed voltage peaks are determined. The intensity and average time of each voltage peak is then determined and the intensity and time values are stored. An intermediate composite mass spectrum is then formed by combining the intensity and time values which relate to each voltage peak observed from multiple experimental runs. The various pairs of time and intensity data are then integrated to produce a smooth continuum mass spectrum. The continuum mass spectrum may then be further processed by determining the second differential of the continuum mass spectrum. The start and end times of mass peaks observed in the continuum mass spectrum may be determined. The intensity and mass to charge ratio of each mass peak observed in the continuum mass spectrum may then determined. A final discrete mass spectrum comprising just of an intensity value and mass to charge ratio per species of ion may then be displayed or output.
    • 公开了一种质谱法,其中分析了来自离子检测器的电压信号。 获得每个电压信号的第二差分,并且确定观察到的电压峰值的开始和结束时间。 然后确定每个电压峰值的强度和平均时间,并存储强度和时间值。 然后通过组合与多个实验运行中观察到的每个电压峰值相关的强度和时间值来形成中间复合质谱。 然后将各种时间和强度数据对被整合以产生平滑的连续质谱。 然后可以通过确定连续质谱的第二差分来进一步处理连续质谱。 可以确定在连续质谱中观察到的质量峰的开始和结束时间。 然后可以确定在连续质谱中观察到的每个质量峰的强度和质荷比。 然后可以显示或输出包括仅每个离子种类的强度值和质荷比的最终离散质谱。

    • A method of mass spectrometry is disclosed wherein an Electron Collision Dissociation, Electron Transfer Dissociation or Surface Induced Dissociation fragmentation device is repeatedly switched between a high fragmentation mode and a low fragmentation mode. Parent ions from a first sample are passed through the device and parent ion mass spectra and fragmentation ion mass spectra are obtained. Parent ions from a second sample are then passed through the device and a second set of parent ion mass spectra and fragmentation ion mass spectra are obtained. The mass spectra are then compared and if either certain parent ions or certain fragmentation ions in the two samples are expressed differently then further analysis is performed to seek to identify the ions which are expressed differently in the two different samples.

    • PROBLEM TO BE SOLVED: To provide an identifying method of a candidate parent ion suitable to identify the candidate parent ion in a real time and to use for a chromatography. SOLUTION: An improving method of a parent ion scanning is disclosed. In one embodiment, a quadruple mass filter 3 of an upstream of a collision cell 4 is arranged to work in a high pass mode. The parent ion passed the mass light filter 3 is fragmentized by a collision cell 4, and is discovered by an orthogonal type time of flight analyzer 5 to acquire daughter ion spectra. Ions having mass/charge ratio of not more than cutoff value of the mass light filter 3 are identified as the daughter ions, and the candidate parent ion is subsequently discovered, and by acquiring corresponding daughter ion spectra, their identifications can be confirmed. In the first embodiment, because the collision cell is switched in alternation in a space of a high or low fragmentation, and further, the candidate parent ion can be identified based on a dissipation of a prescribed ion or a neutral particle.
