    摘要: An electrostatic lens (3), including five cylindrical electrodes (31-35) arrayed along an ion-optical axis (C) and an aperture plate (38) located on a common focal plane of two virtual convex lenses (L1 and L2) formed under an afocal condition, is used as an ion-injecting optical system for sending ions into an orthogonal acceleration unit. The diameter of a restriction aperture (39) formed in the aperture plate (38) determines the angular spread of an exit ion beam. When voltages for making the electrostatic lens (3) function as an afocal system are set, a measurement with high mass-resolving power can be performed at a slight sacrifice of the sensitivity. When voltages for making the lens function as a non-afocal system having the highest ion-passage efficiency are set, a measurement with high sensitivity can be performed at a slight sacrifice of the resolving power.

    摘要: A technique for improving the mass-resolving power of an ion trap time-of-flight mass spectrometer is provided. At the final stage of a cooling process before the ejection of ions from an ion trap, the frequency of a rectangular-wave voltage applied to a ring electrode of the ion trap is increased for a few to several cycles. This operation reduces the confining potential depth of the ion trap and decelerates the captured ions. The turn-around time of the ions is shortened when the rectangular-wave voltage is halted and an accelerating electric field is created. Thus, the variation in the time of flight of the ions with the same mass-to-charge ratio is reduced. The time for increasing the frequency is determined so that a spread of the ions because of the depth reduction of the confining potential will fall within the range that can be corrected in the time-of-flight mass spectrometer.

    摘要: In performing an isolation of specific ions or performing a dissociation operation by CID, ions are captured by applying a radio-frequency high voltage to a ring electrode 31 as before. In a cooling operation which is performed immediately before target ions are ejected toward a TOFMS unit 4 with the ions stored in an ion trap 3, a radio-frequency high voltage is not applied to the ring electrode 31 but to end cap electrodes 32 and 34 to capture the ions. In this operation, the frequency thereof is set to be higher than that of the voltage applied to the ring electrode 31 and the amplitude is also increased in order to assure a large pseudopotential and keep the low mass cutoff (LMC). This narrows the spatial distribution of the cooled ions, reducing the variation of the initial positions of the ions at the point in time when they are ejected, which increases the mass resolution. In addition, since an isolation of ions having a large m/z can be performed with a great qz value as is conventionally done, a high mass selectivity can be assured.

    摘要: A technique for performing precursor isolation with a desired mass-to-charge ratio (m/z) in a digital ion trap while maintaining the q value at a substantially constant value is provided. A data obtained by digitizing an FNF signal having a notch is stored beforehand in an FNF waveform memory 15. In the process of precursor isolation, a main voltage timing controller 7 and a main voltage generator 9 generate a rectangular-wave voltage based on a reference clock signal CK. An auxiliary signal generator 14 reads data from the FNF waveform memory 15 and generates an FNF signal by performing digital-to-analogue conversion of the data in accordance with a clock signal synchronized with the reference clock signal CK. Under the command of a controller 30, a reference clock generator 6 produces the reference clock signal CK having a frequency corresponding to the m/z value of a target ion. Accordingly, a change in the m/z of the target ion leads to a change in the frequency of the reference clock signal CK, which causes the frequency of the rectangular-wave voltage and the central frequency of the notch of the FNF signal to change in the same proportion.

    摘要: When ions are introduced from outside into the ion trap space, a static electric field having equi-voltage surfaces concave to the entrance hole is formed in the ion trap space. For ions obliquely entering the ion trap space, such a static electric field makes the ions cross the equi-voltage surfaces at almost perpendicular angles. Owing to such configuration, ions are effectively decelerated, and enough time can be secured until ions of larger mass-to-charge ratios assuredly enter the ion trap space.

    摘要: When ions accumulated in the exit side end of ion guide are to be injected into ion trap as packets, the application of square wave high frequency voltage to ring electrode from main voltage generating unit is stopped. Once nearly all the ions have been injected into ion trap, the application of square wave high frequency voltage from main voltage generating unit to ring electrode is momentarily started, at which time the application of square wave high frequency voltage is started from a phase in the range of 90°±40° or 270°±40°. It is thereby possible to reduce the extent of spread of ions immediately after application of high frequency voltage and to improve the ion trapping efficiency.
