摘要： In estimating a structural formula of an unknown substance produced through partial structural change of an original substance having a known structure caused by metabolism or the like, structural change is considered in two stages, the elimination of a partial structure and the addition of another partial structure. First, an additional partial structure is collected as known information in addition to an MSn spectrum of the unknown substance and a structural formula of the original substance. A structural formula at the time when a partial structure is eliminated from the original substance is estimated, and a structural formula of each of product ions is estimated. The structural formula of the unknown substance is determined by estimating a structure that can produce the candidates for structural formulas of the product ions by dissociation.

摘要： From the data obtained by an LC/MS analysis in which an automatic MSn analysis is performed, all MS2 spectrum data are collected (S1), and a data matrix is created whose elements are peak intensity data with different precursor ions being arrayed in the horizontal direction and the mass-to-charge ratio of the product ions in the vertical direction (S2). By using the data in this data matrix, the correlation coefficients between two precursor ions are computed to create a correlation coefficient matrix (S3). In the correlation coefficient matrix, the diagonal elements whose value is “1” are all replaced by “0” to create an adjacency matrix (S4). A network analysis is performed for the adjacency matrix to create a network map showing the correlations among different precursor ions (MS2spectra) (S5). The network map is displayed on a window of a display unit simultaneously with the result of an MS1 analysis to provide an analysis operator with information on the compounds contained in a sample or the structure thereof (S6).

摘要： A sample solution containing a sample component is sprayed onto an atmosphere at atmospheric approximately pressure while being applied with electric charge from the tip of a nozzle (1). A sample molecule is released as an ion in a process where charged minute liquid droplets collide with an atmospheric gas and are broken apart, and a solvent is vaporized from the respective liquid droplets. A reflectron (7) in the shape of a half-cut spheroid is arranged in such a manner that a second focal point (F2) is positioned in front of an ion-introducing portion (4) in the spray flow. A discharge electrode (8) is disposed in a position at a first focal point (F1) of the reflectron (7). When pulsed high voltage is applied to the discharge electrode (8), an electric discharge occurs, causing shock waves to be generated. The shock waves reflected on the reflectron (7) are converged on the second focal point (F2). Due to the converged shock waves, the vicinity of the second focal point (F2) rises to a high temperature, and a large pressure is also applied thereto. Therefore, vaporization of a solvent from the respective liquid droplets is further accelerated, allowing an ion to be easily generated. In addition, direct ionization can be expected. This makes it possible to improve ion generation efficiency.

摘要： In a two-dimensional LC system configured to introduce components trapped in a trap column during a fractionation period T into a second-dimension column, separate components, and then detect the components using a mass spectrometer, a data collection unit receives a signal which indicates timing to delimit the fractionation period T, determines the first data item in the fractionation period T, adds measurement start point identification information to the first data item, and stores all the data in a data storage unit. A two-dimensional chromatogram creation unit recognizes the first data item in each fractionation period T from the read data, and create a two-dimensional chromatogram by aligning data so that the first data items will be aligned at the top along an abscissa.

摘要： A molecular weight is determined from an actually measured mass spectrum of a target substance, and a database search is performed to extract candidates of a chemical structural formula corresponding to the molecular weight (S2, S3). By using an algorithm for predicting a dissociation pattern, product ions to be produced by a dissociating operation are predicted for each candidate of the chemical structural formula (S4). The predicted pattern of the product ions is compared with an actually measured MS2 spectrum, and a degree of similarity representing the degree of matching of the pattern is calculated (S5). When there are a plurality of candidates of the chemical structural formula, the candidates are displayed in order of their degrees of similarity (S6).

摘要： Data for a plurality of samples collected by an LC/MS, GC/MS or other systems are converted into a two-dimensional table format without losing information and with a light load, thereby allowing a multivariate analysis processing to be efficiently performed. After LC/MS data on a plurality of samples are obtained and the respective extracted ion chromatograms (XICs) are created (S1 and S2), the correction of the retention-time difference, the waveform processing and the like are performed (S3 and S4), followed by the creation of a one-dimensional table in which the signal-strength values are arranged for each XIC. Then, one-dimensional tables of a plurality of XICs for one sample are joined together in order of m/z value to create an elongate one-dimensional table (S5). The elongate one-dimensional tables of a plurality of samples are arranged in another dimensional direction to obtain a two-dimensional table (S6).

摘要： Ions originating from sample components are made to fly along a loop orbit (P) multiple times, and are deviated from the loop orbit (P) when a predetermined period of time has elapsed after the ejection of the ions. A time-of-flight spectrum recording unit (81) creates a time-of-flight spectrum based on the detected signal. If an overtaking of ions occurs on the loop orbit (P), the number of turns of peaks (ions) appearing on the spectrum cannot be determined. Given this factor, an isotopic peak detector (82) finds an isotopic peak group based on the time intervals and intensity ratio of a plurality of peaks appearing on the spectrum. A flight distance computation unit 83 uses the fact that the mass difference between adjacent peaks belonging to an isotopic peak group is 1 Da when ions are singly-charged, and computes the flight distance based on a predetermined formula. From the flight distance, a mass computation unit (84) computes the number of turns, and recomputes the flight distance which is structurally determined from this number of turns. Then, the mass computation unit (84) computes the mass of the target component. This enables an acquisition of the accurate mass free of the influence of an overtaking of ions and other factors.

摘要： A first mass analysis is executed in a condition that gas is not introduced into a loop-flight chamber (4), and a time-of-flight spectrum obtained in a data processor (12) is stored in a storage unit (13). Next, a second mass analysis is executed on the same sample as the one used in the first mass analysis in a condition that a valve (8) is opened and helium gas (He) is introduced into the loop-flight chamber (4), and the time-of-flight spectrum is obtained in the data processor (12). If different kinds of ions having the same m/z value exit, these ions form a single peak in the first time-of-flight spectrum, while these ions appear as separate peaks in the second time-of-flight spectrum even though they have the same m/z value. This is because, in the second mass analysis, the ions collide with the gas and have different times of flight depending on their difference in size. A spectrum comparator (14) judges a change in the position or shape of the peak by comparing the two spectra, and outputs information relating to the difference in the size of the ions (the molecular structure, charge state, or molecular class of the ions), and the like. Accordingly, a wider variety of information than ever before can be provided.
