Title:
ION OPTICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/187880
Kind Code:
A1
Abstract:
An ion optical device of the present invention comprises one or more pairs of confinement electrode units arranged opposite to each other at two sides of a first direction in a space and extending along the first direction; a power supply device for applying opposite radio-frequency voltages to the paired confinement electrode units respectively and forming on the confinement electrode units a plurality of DC potentials which are distributed in a second direction substantially orthogonal to the first direction so as to form a potential barrier in the second direction over at least a portion of the length of the first direction; at least one first area and at least one second area positioned in the space at two sides of the potential barrier in the second direction; and a control device connected with the power supply device for controlling an output of the power supply device to change the potential barrier so as to manipulate the ions transported or stored in the first area to be transferred to the second area through the potential barrier in different ways based on the mass to charge ratio or mobility of the ions and continue to be transported along the first direction, thereby improving the ion utilization efficacy of other downstream devices operating synchronously therewith.
