摘要： PROBLEM TO BE SOLVED: To improve mass accuracy of a mass spectrometer having a go-around track.
SOLUTION: A detector 5 of an ion-nondestructive type is set on a go-around track A of ion, times of flight are measured for each round until the ion as an object for analysis goes around for N times, and time-of-flight spectra are made where a peak at each going around shows itself. Alternatively, a time of flight for each going around is measured according to detection signals by an ion-nondestructive detector 4 by changing the number of times of going around for each ion irradiation from an ion source for 1 to N rounds, and the time-of-flight spectra showing a peak at each round are made by combining it. A data processing unit 7 converts the spectrum data into a wavelength axis by Fourier transformation, and finds out peaks of frequencies corresponding to the number of mass to calculate the number of the mass from the frequencies.

摘要： PROBLEM TO BE SOLVED: To measure the kinetic energy of a charge particle of ion or the like with high resolution by using an orbit in which multiple circulation is possible. SOLUTION: The orbit is formed as the primary position and primary angle of ion converge in time but the kinetic energy of ion does not converges in time every when ion circulates two times using a plurality of troidal electronic fields E1 and E2. A high ion transmittance is realized by converging ion in space in every two circulations in horizonal plane including the orbit without depending on the primary position, primary angle or primary kinetic energy, and by making the orbit that does not disperse even in vertical plane. Thereby, the flight time becomes depend only on the kinetic energy, and more the ion circulated the orbit the more the energy resolution increased. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To determine a mass number of ions for which catching-up and overtaking have occurred along the way without limiting a mass range of the ions to be put on an orbit. SOLUTION: At least two analysis conditions (Tg=500 [μs], 400[μs]) where a difference in round numbers is generated in relation to targeted ions are set, and measurement is executed by using them; and the time of flight is obtained from time-of-flight spectrum information obtained from the two measurements. Since the round number itself is unknown but a plurality of candidate mass numbers corresponding to each round number can be obtained from the time of flight, the candidate mass numbers obtained from the times of flight (500 [μs] and 400[μs]) by measuring twice are compared with one another, and coincident one is selected to determine it as the mass number. Thereby, the mass number can be obtained even if the mass range is not limited before putting the ions on the orbit. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To change mass resolution accordingly adapting to the purpose of analysis without any change or addition to a complicated mechanical constitution in TOFMS constituted to have ion fly along a spiral orbit.
SOLUTION: Deflecting electrodes 20 to 23 for generation of an electric field to shift the ion in the axial direction of cylindrical electrodes is installed in between the cylindrical electrodes 11, 12 to have the ion fly spirally. Voltage applied to the deflecting electrodes 20 to 23 are varied adapting to the necessary mass resolution. When the deflection electric field is generated or extinguished by the change in the voltage, since the ion is made to fly on the spiral orbit (c), or circulate on the same orbit (b), the flying distance can be accordingly controlled by adjusting the circulating number arbitrarily and thus the mass resolution can be controlled.

摘要： PROBLEM TO BE SOLVED: To provide a laser irradiation mass spectrometer capable of carrying out mass spectrometry of a bio-organization and a component of in-vivo cell. SOLUTION: The laser irradiation mass spectrometer irradiates a laser beam to a test piece by controlling the irradiation position and carries out mass spectrometry of ions of the test piece generated there, and obtains the position information of the test piece and the mass spectrometry information in that position. For that mass spectrometry, a frequency drive type ion trap and a time of flight mass spectrometer are used. Thereby, ions with high mass number can be certainly trapped and can make them an object for analysis. It is desirable that a digital drive method is used for the drive method of the frequency drive type ion trap. Furthermore, it is desirable that a multi-turn type time of flight mass spectrometer is used. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a mass spectrometer with the resolution of MS/MS analysis improved.
SOLUTION: Various types of ions generated in an ion generating section 1 are introduced into an ion trap 3, are kept there, and after that, are discharged toward TOFMS4. The ions are separated by the mass numbers during flight in a flying space 42, and only the ions, having the specific mass numbers, return to the ion trap 3 via an ion lens 37 from a deflector electrode 5. Trajectories of other ions are bent by the deflector electrode 5, and the bent ions are discarded. Only the targeted ions are kept in the ion trap 3, because the mass resolution of the TOFMS4 is high. After that, a CID gas is introduced into the ion trap 3, and the ions are dissociated in an ion-capturing space 34. Various types of dissociated ions are separated by the TOFMS4 according to their respective masses, and the separated ions are bent so as to trace a trajectory T2 by the deflector electrode 5. This time, they are introduced into a detector 6. Since the dissociated ions that only originate from the target ions with which impure ions are not mixed, are analyzed with high resolution using the mass spectrometer, high precision analysis can be performed.

摘要： PROBLEM TO BE SOLVED: To carry out structural analysis of molecules by selecting target ions with a high mass resolution and analyzing ion fragments generated by cleaving the target ions. SOLUTION: Various kinds of ion generated at an ion source 1 are put on a revolving track P, differences of the target ion and the other kinds of ion are enlarged during the process of revolution, and unnecessary kinds of ion are discarded out of the track by a deflection electrode. Thereby, the target ion alone is left on the track with a high mass resolution, and a higher performance is realized with a function virtually equal to ion trapping. The target ion of high purity thus stored is turned aside from the track P, led to a second flight space 6 after being cleaved at a cleaving region 4, and is folded back with a reflector 7 at a position corresponding to the number of mass to be detected with a detector 8.

摘要： PROBLEM TO BE SOLVED: To reduce the amount of data collected in a mass spectroscope having an orbit.
SOLUTION: Only time measurement is executed during a period from a point of time ions are emitted from an ion source 1 to application of a voltage for making the ions leave from an orbit A after circulating the orbit A a predetermined number of times to a gate electrode 21. From a point of time timing is set at Tg and the application voltage to the gate electrode 21 is changed, a data processing part 6 starts collection of detection data by an ion detector 3 and starts to store them into a memory 61. Since the output of the detector 3 is not significantly changed until timing is set at Tg, a memory can be saved by remarkably reducing the amount of data without impairing accuracy and the like.
