Abstract

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.
