Ion transfer device

摘要

There is provided a transfer device (30) that transfers ionized substances in a first direction. The transfer device (30) includes a drift tube (50) and the drift tube (50) includes electrode plates (71) and (72) constructing an outer wall and a plurality of ring electrodes (60, 61, 62) disposed inside the tube. The ring electrodes (60) forms a first AC electric field for linear driving that causes the ionized substances to travel in the first direction that is the axial direction. The electrode plates (71) and (72) form an asymmetric second AC electric field that deflects the direction of travel of the ionized substances.

主权项

1. An apparatus comprising a transfer device that transfers ionized substances;
the transfer device comprising:
a plurality of ring-shaped first electrodes disposed in a line in a first direction, with voltages of different polarities being applied to adjacent electrodes of the plurality of first electrodes, to form a plurality of first alternating current electric fields for linear driving that causes at least some of the ionized substances to travel in the first direction;a plurality of second electrodes that are disposed outside the plurality of first electrodes, are aligned in a second direction that is perpendicular to the first direction, and form at least part of a flow path of the ionized substances, the plurality of second electrodes forming a common second alternating current electric field in a direction that is perpendicular to the plurality of first alternating current electric fields formed by the plurality of first electrodes and forming the second alternating current electric field that is asymmetric and deflects a direction of travel of the at least some of the ionized substances in the second direction; the apparatus further comprises:
an ionization unit that ionizes one or more substances introduced into the transfer device;a detector that detects one or more substances ejected from the transfer device; andan accumulator that accumulates one or more substances within the transfer device; wherein the transfer device further includes:
a first unit that can deliver the one or more substances to the accumulator;a second unit that can deliver the one or more substances to the detector; anda bent unit that connects the first unit and the second unit.
