摘要： A linear trap having high ejection efficiency and low ejection energy is realized. In a mass spectrometer in which ion generated by an ion source are introduced to a quadrupole rod structure applied with RF voltage and ejected from the quadrupole rod structure so as to be detected by a detection mechanism, a mass dependent potential is formed in the axial direction of the quadrupole rod structure and ions are ejected mass selectively from the vicinity of a minimum point of the potential, the mass dependent potential being formed by applying electrostatic voltage and RF voltage to an insertion electrode inserted in the quadrupole rods.

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： Provided is a technique of analyzing particles in real time while collecting and condensing the particles continuously. Gas and/or particles as a detection target substance that are attached to an authentication target 2 are removed by air flow from a blowing region 5. The removed sample is sucked and is condensed and sampled at a sampling region 10, and ions of the sample are generated at an ion source 21 and are then subjected to mass analysis at a mass analysis region 23. Determination of the obtained mass spectrum is made as to the presence or not of a mass spectrum derived from the detection target substance, and a monitor 27 displays a result thereof. Thereby, the detection target substance attached to the authentication target 2 can be detected continuously in real time, promptly and with a less error rate.
