Abstract
A switch for coupling a first ion manipulation device to a second ion manipulation device comprises a first surface and a second surface, at least one first electrode coupled to each of the first and second surface and configured to receive a first voltage and generate a first potential, and at least one second electrode coupled to each of the first and second surface and configured to receive a second voltage and generate a second potential, wherein the first potential inhibits the motion of ions along a first direction and the second potential inhibits the motion of ions along a second direction different from the first direction.

A switch for coupling a first ion manipulation device to a second ion manipulation device comprising:
- a first surface and a second surface;
- at least one first electrode coupled to each of the first and second surface and configured to receive a first voltage and generate a first potential;
- and
- at least one second electrode coupled to each of the first and second surface and configured to receive a second voltage and generate a second potential;
- wherein the first potential inhibits the motion of ions along a first direction and the second potential inhibits the motion of ions along a second direction different from the first direction.
An ion manipulation device comprising:
- a constant-field portion oriented in a first direction and configured to guide ions along the first direction;
- a traveling wave portion oriented in a second direction different from the first direction and configured to guide ions along the second direction;
- a switch portion;
- and
- a controller coupled to the switch;
- wherein the constant-field portion and the traveling wave portion are positioned in a substantially T-shaped configuration and the switch portion is positioned at a junction between the constant-field portion and the traveling wave portion;
- wherein the constant-field portion comprises a first constant-field portion on one side of the switch and a second constant-field portion on the other side of the switch;
- wherein the switch is configured to be operable in a first mode of operation and a second mode of operation, wherein, in the first mode of operation, ions entering the switch from the first constant-field portion move through the switch and enter the second constant-field portion, and, in the second mode of operation, ions entering the switch from the first constant-field portion move through the switch and enter the traveling wave portion.
A method of manipulating ions, comprising:
- coupling a first ion manipulation device and a second ion manipulation device to a switch, wherein the first ion manipulation device is oriented along a first direction and the second ion manipulation device is oriented along a second direction;
- and
- applying a voltage to the switch to cause ions travelling from the first ion manipulation device towards the switch to enter the second ion manipulation device after entering the switch.
