    摘要: A product ion spectrum is created on the basis of MS2 analysis data respectively obtained for a parent compound and a metabolite (S1 and S2). Additionally, a neutral loss spectrum, in which the mass of each product ion is replaced with a mass difference between the mass of the product ion and that of a precursor ion, is created (S3). Then, a common peak having the same mass on the neutral loss spectrums of both the parent compound and the metabolite is extracted (S4), and a complementary peak appearing on the product ion spectrum of the metabolite is extracted (S5); this peak appears at a position corresponding to the difference between the mass of the common peak and that of the precursor ion. The ion corresponding to the complementary peak is designated as a precursor ion for the next MS3 analysis (S6), and this MS3 analysis is performed (S7). By a dissociation operation, if a portion common to the parent compound and the metabolite is desorbed in the form of a neutral molecule while a different portion remains in the form of an ion, an MS3 analysis in which the ion of the different portion is used as the precursor ion is performed to obtain structural information of a site of metabolism.

    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: When the analyzer provides the mass and composition formula of the product ion, which is probably produced in the process of a dissociation, through the input unit, based on known information, a composition formula list is created in the database. When a product ion is obtained in an MSn analysis, the data processor checks whether or not the ion's mass exists in the composition formula list, and in the case where it does, the composition formula corresponding to the mass is determined. Then, based the mass difference between the precursor ion and product ion or other factors, the precursor ion's composition formula is deduced, and if it is possible to ultimately narrow down the candidates for the target ion's composition formula, the analysis is terminated. Accordingly, if the composition formula list is available, the refinement operation for the candidates for the composition formula can be omitted.

    摘要: A variety of ions generated in an ion source are made to fly while bypassing a loop orbit and mass analyzed to create a mass spectrum. Among the peaks appearing on the mass spectrum, peaks complying with predetermined conditions are extracted to determine a plurality of mass ranges to be measured (S1 through S3). Next, the ion selection conditions for the timing when ions should be injected into the loop orbit and on the loop orbit are determined for each mass range. In addition, deviation conditions under which selected ions will not be mixed are determined (S4 and S5). When the second measurement is performed for the same sample, ions are put into the loop orbit and unnecessary ions are removed from the loop orbit in accordance with the ion selection conditions (S6 and S7). Thus, only the ions to be measured are left on the loop orbit with a high mass resolving power. Then, these ions are sequentially deviated from the loop orbit in accordance with the ion deviation conditions, dissociated, and then mass analyzed (S8). In this manner, MS/MS analyses are performed for each of the plurality of ions to be measured to create an MS/MS spectrum (S10).

    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: The present invention provides a time of flight mass spectrometer having an ion optics forming a multi-turn track, which is capable of time-focusing the ions while allowing the multi-turn track to be configured in an unlimited and highly variable manner. In a specific form of the invention, a reflector 9 is provided on the flight path between the position where the ions leave the loop orbit P and the ion detector 10 located outside the loop orbit P, and the condition of the electric field generated by the reflector 9 is appropriately determined. Thus, even if the ions cannot be well time-focused by the ion optics 2 creating the sector-shaped electric fields 4 and 7, it is possible to compensate the time-focusing performance with the reflector 9 to achieve a good performance of time-focusing of the ion throughout the overall system wherein the ions leave the ion source 1 and finally reach the ion detector 10. Thereby, the ions can reach the ion detector 10 at approximately the same time even if the ions having the same mass number have different levels of energy at the moment they leave the ion source 1.
