摘要： In an ion mobility separation device, there are problems that while arraying of separation electrodes and flow paths is restricted, time required for scanning correction voltages becomes longer and the throughput is reduced when the correction voltages are set in detail. These problems are solved for example by the following means. Namely, an ion mobility separation device characterized in that: at least one of a pair of plate electrodes has a first electrode section having a first conductivity, a second electrode section having a second conductivity, and a third electrode section interposed between the first electrode section and the second electrode section, wherein the third electrode section has a third conductivity smaller than the first conductivity and the second conductivity; the first electrode section, the second electrode section and the third electrode section are aligned in a direction perpendicular to a flow path; and a voltage controller applies different direct-current voltages to the first electrode section and the second electrode section.

摘要： A linear trap which allows for charge separation and ion mobility separation in a speedy manner, and enables measurement with high duty cycle. A mass spectrometer comprises an ion source, an ion trap for trapping ions ionized by the ion source, an ion trap controller for controlling a voltage on an electrode included in the ion trap, and a detector for detecting the ions ejected from the ion trap. The ion trap controller includes a table for each mass-to-charge ratio, the table containing a frequency of the voltage used for charge separation, and a gain of the voltage for ejecting a first ion with a first charge outside the ion trap, and retaining in the ion trap a second group of ions with a second charge that is lower than that of the first charge. The ion trap controller controls the voltage based on the mass-to-charge ratio set. The mass spectrometer has significantly improved sensitivity, as compared to the prior art.

摘要： In a mass spectrometer in which a high ion dissociation efficiency is possible, inserted electrodes are arranged with a form divided into two or more in the axial direction of the ion trap, an electric static harmonic potential is formed from a DC voltage applied to the inserted electrodes, and with an Supplemental AC voltage applied, ions in the ion trap are oscillated between the divided inserted electrodes in the axial direction of the ion trap by resonance excitation, and the ion with a mass/charge ratio within a specific range is mass-selectively dissociated. Thus, a high ion dissociation efficiency is realized by the use of ion trap of the present invention.
