    • The main voltage generator (5) applies a rectangular-wave radio-frequency voltage to the ring electrode (21) in order to capture ions inside the ion trap (2). In the case where the TOFMS (3) is operated in the reflectron mode, the radio-frequency voltage is changed into a constant voltage value when the phase thereof is 1.5π, and a voltage for expelling ions is applied to the end cap electrodes (22, 23) to expel the ions from the exit aperture (25) and introduce them into the TOFMS (3). In this case, since the velocity spread of the ions inside the ion trap (2) is small and so is the spatial spread thereof, a high mass resolution and accuracy can be achieved while assuring a high detection sensitivity. In the case where the TOFMS (3) is operated in the linear mode, the radio-frequency voltage is changed into a constant voltage value when the phase thereof is 0.5π, and then the ions are expelled. In this case, a high mass resolution and mass accuracy can be achieved since the variation of the ions' acceleration, which cannot be converged in the linear mode, can be suppressed.

    • The number of times of repetition of mass spectrometry analysis for integrating mass profiles is reduced to facilitate reduction in measurement time-period and increase a signal intensity. In a state when ions are trapped by a high-frequency electric field formed within an ion trap, a rectangular-wave high-frequency voltage to be applied from a main voltage generation section to a ring electrode is temporarily stopped, and next ions are introduced from an ion entrance port into the ion trap in a state when only a static electric field exists within the ion trap. The high-frequency voltage application is re-started while at least a part of previously-trapped ions remain within the ion trap, to trap the newly-introduced ions in addition to the previous ions so as to increase an amount of ions to be accumulated, and the accumulated ions are subjected to the mass spectrometry analysis.

    • Disclosed is a mass spectrometry apparatus and method capable of providing enhanced analysis sensitivity in a mass spectrometric analysis for a small amount of ions. A quadrupole rod-type ion guide is employed to temporarily accumulate ions to be introduced into an ion trap, and ions are introduced into the ion guide in an amount less than a saturated ion amount in the ion guide, and accumulated in an exit end of the ion guide. As compared with an octopole rod-type ion guide, the quadrupole rod-type ion guide has a higher ion-converging capability, and therefore can confine and hold a small amount of ions around an ion optical axis, although it is inferior in ion-accumulating capability. This makes it possible to efficiently introduce the ions into the ion trap through two openings of an electric field-correcting electrode and an entrance endcap electrode, so as to perform a high-sensitive analysis.

    • A samples stage (2) on which a sample (4) is placed can reciprocally move along a guide (5) by a driving mechanism. An image taken by an imaging unit (7) when the sample stage (2) is at an observation position (A) is processed by an image processor (34) and is displayed on a window of a display unit (38). When an analysis operator specifies a measurement area by an operation unit (37), a controller (3) moves, through a stage driver (33), the stage (2) to a sample operation position (B) and a matrix is applied to the specified measurement area by an ejector (9). After that, the stage (2) is moved to an analysis position (C) and a laser light is delivered onto the measurement area on the sample (4) to which the matrix was applied, and the ionization by the MALDI method is performed. This eliminates the need to take out the sample from the apparatus to apply the matrix after the measurement point or measurement area is determined based on a microscopic observation of the sample. Accordingly, the efficiency of the measurement can be increased, and since no positional error of the sample occurs, it is possible to perform an imaging mass analysis for a measurement area of interest with high positional accuracy.
