摘要： Provided is a time-of-flight mass spectrometer having a reflectron which eliminates energy dependency of the flight time of ions having the same m/z while ensuring a high degree of design freedom. An electric field created by the reflectron is virtually divided into a decelerating region for decelerating ions and a reflecting region for reflecting ions. For an ion having a mass-to-charge ratio which has departed with initial energy higher than Ud, the total flight time required for the ion to travel through a free-flight region and the decelerating region into the reflecting region and return will be equal to the total flight time required for an ion of the same mass-to-charge ratio to make a round trip in which the ion turns around at a point of the reference potential value at the boundary between the decelerating region and the reflecting region or in the decelerating region.

摘要： One virtual rod electrode is composed by a plurality of electrode plane plates arranged in the ion optical axis direction, and four virtual rod electrodes are arranged around the ion optical axis to form a virtual quadrupole rod type ion transport optical system (30). In one virtual rod electrode, the interval between the adjacent electrode plane plates is set to be large in the anterior area (30A) and small in the posterior area (30B). As the interval between electrodes becomes larger, high-order multipole field components increase and therefore the ion acceptance is increased, which enables an efficient acceptance of ions coming from the previous stage. On the other hand, if the interval between electrodes is small, the quadrupole field components relatively increase and the ion beam's convergence is improved. Therefore, ions can be effectively introduced into a quadrupole mass filter for example in the subsequent stage, which contributes to the enhancement of the mass analysis' sensitivity and accuracy.

摘要： A mass spectrometer is provided in which ions are favorably introduced into a loop orbit or favorably led out from the loop orbit without affecting the motion of the ions flying along the loop orbit. An ion-introduction orbit 5 is set to correspond to the orbit (ejection orbit portion 4) of ions after being bent by the sector-shaped electric field E1 in the loop orbit 4. When ions are introduced, a voltage applied to the electrode unit 11 is put to zero to release the sector-shaped electric field E1. Then the ions emitted along the ion-introduction orbit 5 fly straight in the electrode unit 11. The direction and position of the ions coming out from the exit end of the electric field is the same as those ions flying along the loop orbit 4. Therefore, there is no need for placing a deflection electrode for introducing/leading-out ions on the loop orbit.

摘要： A basic ion optical system (2) in which the temporal focusing of ions is ensured includes a plurality of sector-shaped electrodes (11, 12, 13, and 14), an ion injection slit (15), and an ion ejection slit (16), which are placed on the same plane. A plurality of basic ion optical systems (2) are placed in such a manner as to be mutually separated at predetermined intervals in the direction approximately orthogonal to their planes. The ion ejection slit (16) of the lower-stage basic ion optical system (2) and the ion injection slit (15) of the next-stage basic ion optical system (2) are connected to each other via another basic ion optical system (3) in which the temporal focusing of the ions is ensured. Accordingly, the flight distance can be elongated while assuredly achieving the temporal focusing of the ions as an entire ion optical system (1), and a three-dimensional space can be efficiently utilized to compactify the ion optical system (1).

摘要： One virtual rod electrode (11) is composed by arraying a plurality of plate electrodes (111, . . . , 118) along an ion beam axis, and a quadrupole ion optical element (1) is constructed by arranging four virtual rod electrodes (11, 12, 13 and 14) around an ion beam axis C. A voltage-applying unit alternately applies two radio-frequency voltages having a phase difference of 180 degrees for each of the plate electrodes in one virtual rod electrode. By this voltage application, the quadrupole component of the radio-frequency electric field created within a space surrounded by the four virtual rod electrodes is decreased, while higher-order multipole components are increased. The quadrupole component yields high ion convergence and mass selectivity, while the higher-order components provide high ion transmission efficiency and ion acceptance. The general ion transport efficiency can be improved by appropriately adjusting the ion optical characteristics according to the installation environment of the ion optical system and the conditions before and after the ion optical system.
