  • Mass spectrometer equipped with MALDI ion source and sample plate for MALDI ion source
    Patent number: 7855359
    Abstract: A mass spectrometer is equipped with a MAILDI ion source facilitating both individual management of sample plates and mass calibration based on information about distortion in the sample plates. Also, sample plates adapted to be used in the MALDI ion source are provided. Identification information about each sample plate and information about distortion, i.e., topography, in the surface of the sample plate are engraved on the surface of the sample plate. These sets of information are also registered as an electronic file. During measurement, these sets of information are read by observation means and used for individual management of sample plates and mass calibration of mass spectra.
    Type: Grant

    Date of Patent: December 21, 2010
    Assignee: JEOL Ltd.

  • Detector using microchannel plates and mass spectrometer
    Patent number: 7049605
    Abstract: A mass spectrometer detector having a coupling capacitor including an anode that is placed at a high potential of say ?4.9 kV. An annular electrode is placed outside the anode. A voltage of say ?5 kV is applied to the annular electrode. This reduces the potential difference between the anode and the annular electrode, mitigating the electric field. A peripheral electrode is mounted on the outer fringe of a dielectric body and stably held at a potential of say ?2.5 kV, for example, by voltage-dividing resistors.
