Abstract
Ion optical elements in accordance with various aspects of the present teachings can, in various embodiments, be utilized to replace conventional stacked-ring ion optical elements (e.g., ion guides, ion tunnels, ion funnels, reflectrons), which typically contain a plurality of individual conductor rings and insulating spacers that must be manufactured with exacting tolerances and precisely aligned during assembly. In various aspects, methods of producing ion optical elements are also disclosed herein, which according to various aspects may reduce the cost and/or complexity associated with precisely manufacturing and assembling the many parts of conventional stacked-ring devices.
Claims20
An ion optical element, comprising:
- an insulating substrate having an inner channel bounded by an inner surface of the insulating substrate and extending along an axis from a first end to a second end thereof;
- and
- a resistive coil coupled to the inner surface and continuously extending from the first end to the second end of the insulating substrate, wherein maintaining a voltage differential across the resistive coil is configured to generate an electric field within the inner channel for controlling axial motion of ions therein.
A method of manufacturing an ion optical element, comprising:
- forming an insulating substrate from an insulator material, the insulating substrate having an inner channel bounded by an inner surface of the insulating substrate and extending along an axis from a first end to a second end thereof;
- and
- coupling a resistive coil to the inner surface, wherein maintaining a voltage differential across the resistive coil is configured to generate an electric field within the inner channel for controlling axial motion of ions therein.
An ion optic assembly for use in a mass spectrometer, comprising:
- a first ion optic extending from a proximal end to a distal end, said first ion optic having a lumen providing a first ion passageway and a first resistive trace disposed on an inner surface of the lumen, wherein flow of a current through the first resistive trace establishes a first electric field within the first ion passageway,
- a second ion optic extending from a proximal end to a distal end, wherein the proximal end of the second ion optic can be coupled to the distal end of the first ion optic to form said ion optic assembly, said second ion optic further comprising a lumen providing an ion passageway and a second resistive trace disposed on an inner surface of the lumen, wherein flow of a current through said second resistive trace establishes a second electric field within the second ion passageway, and
- a conductive grid positioned between said ion optics and configured to be maintained at a reference electric potential such that said first and second electric fields terminate on said conductive grid.
