    Abstract: PROBLEM TO BE SOLVED: To provide a sample adjusting method for mass analysis due to a matrix assisting laser elimination ionization method for forming the fine crystals of a matrix and a biomolecule such as biomolecule protein or the like on biotissue in order to form ions with high efficiency to enable measurement of high sensitivity. SOLUTION: A matrix solution is preliminarily sprayed on a protein sample to preform the fine crystal layer of the matrix. When the matrix solution is further dispensed on the fine crystal layer, crystals grow using preformed fine matrix crystals as nuclei. Accordingly, very fine homogenous eutectic crystals are formed and mass analysis due to MALDI can be performed with high sensitivity. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To restrain reduction of signal strength of a mass spectrometer/spectrum of the mass spectrometer so that a primary fragment ion generated with photodissociation is secondarily dissociated.
    SOLUTION: An exciting laser beam for triggering photodissociation is irradiated on the center of a capturing zone A in an ion trap 1, and an exciting signal for making the fragment ion excite without exciting a precursor ion is applied on end cap electrodes 12 and 13. Dissociation of the precursor ion effectively starts by receiving irradiation of the exciting laser beam because the selected precursor ion is gathered in the vicinity of the center of the capturing zone A. The fragment ion dislocates an exciting beam irradiation zone B due to greater vibration so that the generated fragment ion is immediately excited with the exciting signal by an action of an exciting electric field. Thus, the fragment ion is hard to receive the exciting laser beam, and therefore, secondary dissociation of the fragment ion is hardly generated.

    Abstract: PROBLEM TO BE SOLVED: To miniaturize a time-of-flight mass spectroscope of a type irradiating laser light on a sample 'a' coated on a sample plate 1 to ionize it, and detecting ion by an ion detector (a micro-channel plate) d, after pulling the ion out with a field gradient formed by an electrode 2 and letting it freely fly. SOLUTION: In the time-of-flight mass spectroscope, at least either the sample plate 1 or the electrode 2 is structured to be convex-shaped toward an analyzing room. When the ion flies in the analyzing room, it can be made dispersed in a direction vertical to its flight direction, and therefore, the ion can be prevented from being centered on a part of the detector even when an interval between the electrode 2 and the detector d is shortened, whereby, downsizing of the spectroscope as a whole can be realized.

    Abstract: PROBLEM TO BE SOLVED: To accurately detect displacement without using a sample plate specially processed when the sample plate is placed on a stage after a matrix is attached, correct the displacement, and implement a correct mass spectrometric analysis of an area designated by an analyst. SOLUTION: When the sample plate 3 is placed on the sample stage 2, an irradiation sign formation control part 22 timely moves the sample stage 2, irradiates the sample plate 3 with a high power laser light in a short time, and forms an irradiation sign at a predetermined position on the sample plate 3. Since the irradiation sign has a unique shape, a microscopic observation image of the irradiation sign is obtained, and saved in an image saving part 32. After the sample plate 3 extracted from the stage 2 is placed on the stage 2 again, the displacement quantity is calculated from a difference between the position of the irradiation sign on the image obtained at the time and the position of the irradiation sign on the image saved in the saving part 32. An analysis position correcting part 24 corrects position information on the area designated by the analyst in response to the found the displacement quantity. COPYRIGHT: (C)2011,JPO&INPIT
