Multipole Ion Guide Having Longitudinally Rounded Electrodes

View page
US Patent:
7491932, Feb 17, 2009
Filed:
Jun 16, 2006
Appl. No.:
11/454263
Inventors:
Rohan A. Thakur - Los Altos CA, US
Maurizio Splendore - Walnut Creek CA, US
Eloy R. Wouters - San Jose CA, US
Assignee:
Thermo Finnigan LLC - San Jose CA
International Classification:
H01J 49/42
B01D 59/44
US Classification:
250292, 250288, 250284
Abstract:
An ion guide having a plurality of spheroidal or similarly shaped electrodes is disclosed. The electrodes are arranged in pairs about a central ion flow axis, and an RF voltage is applied in a prescribed phase relation to create an electric field that focuses and radially confines an ion beam. A defocusing effect associated with the electrode shape may be reduced by placement of a separate skirt electrode immediately downstream in the ion path, or by forming the electrodes in a composite structure, whereby the trailing portion of the electrode is fabricated from or coated with an insulative material.

Apparatus And Method For Providing Ions To A Mass Analyzer

View page
US Patent:
7741600, Jun 22, 2010
Filed:
Nov 17, 2006
Appl. No.:
11/601343
Inventors:
Eloy R. Wouters - San Jose CA, US
Maurizio Splendore - Walnut Creek CA, US
Assignee:
Thermo Finnigan LLC - San Jose CA
International Classification:
H01J 49/00
US Classification:
250288, 250281, 250282
Abstract:
A method and apparatus for directing ions from an ionization source to a mass analyzer is provided. The method includes producing ions from a sample in an ionization source. Some of the ions are transferred to a first region via a passageway that is in fluid communication with the ionization source. Next, some of the ions are sampled from the first region into a second region via an aperture that is defined thorough a partition element. The aperture is centered about a longitudinal axis that passes through an ion transfer element within the second region. An electric field is established for deflecting some of the ions that pass through the aperture of the partition element. In particular, the electric field is directed transverse to the longitudinal axis such that relatively more ions enter an input end of the ion transfer element compared to when the ions are not deflected.

Appl. No.:
12/125013
Inventors:
Michael W. Senko - Sunnyvale CA, US
Viatcheslav V. Kovtoun - Santa Clara CA, US

William Siebert - Los Altos CA, US
Assignee:
Thermo Finnigan LLC - San Jose CA
International Classification:
H01J 3/14
B01D 59/44
US Classification:
250281, 250282, 250286, 250290, 250396 R, 3133601, 31511181, 31511161, 315 539
Abstract:
A device for transporting and focusing ions in a low vacuum or atmospheric-pressure region of a mass spectrometer is constructed from a plurality of longitudinally spaced apart electrodes to which oscillatory (e. g. , radio-frequency) voltages are applied. In order to create a tapered field that focuses ions to a narrow beam near the device exit, the inter-electrode spacing or the oscillatory voltage amplitude is increased in the direction of ion travel.

Electro-Dynamic Or Electro-Static Lens Coupled To A Stacked Ring Ion Guide

View page
US Patent:
7915580, Mar 29, 2011
Filed:
Oct 15, 2008
Appl. No.:
12/252013
Inventors:
Maurizio A. Splendore - Walnut Creek CA, US
Eloy R. Wouters - San Jose CA, US
Michael W. Senko - Sunnyvale CA, US
Paul R. Atherton - San Jose CA, US
Jean Jacques Dunyach - San Jose CA, US
Christopher Mullen - Menlo Park CA, US
Assignee:
Thermo Finnigan LLC - San Jose CA
International Classification:
H01J 49/06
US Classification:
250288, 250281, 250282, 250290, 250292
Abstract:
A device for improved transportation and focusing of ions in a low vacuum or atmospheric-pressure region of a mass spectrometer is constructed from one or more electro-dynamic or electrostatic focusing lenses that is/are coupled to the first electrode of a stacked ring ion guide (SRIG) to which oscillatory (e. g. , radio-frequency) voltages are applied. Such configurations as disclosed herein, minimizes deleterious field effects and/or repositioning problems of desired ion transfer instruments that utilize such stacked ring ion guides by generally configuring the outlet end of the ion transfer device to a desired position within the electro-dynamic or electro-static focusing lens(es).

System For Preventing Backflow In An Ion Source

View page
US Patent:
8058611, Nov 15, 2011
Filed:
Sep 23, 2009
Appl. No.:
12/565598
Inventors:
Eloy R. Wouters - San Jose CA, US
Christopher Mullen - Menlo Park CA, US
Maurizio A. Splendore - Walnut Creek CA, US
R. Paul Atherton - San Jose CA, US
Assignee:
Thermo Finnigan LLC - San Jose CA
International Classification:
H01J 49/26
US Classification:
250288
Abstract:
A system for preventing backflow as part of an ion source arrangement is introduced. Such a system incorporates a novel continuous flow guide within a source, such as an API ion source. In the spray direction, the cross-sectional area that defines the first portion of the internal volume initially decreases in a convergent-like manner and thereafter increases in a divergent-like manner towards the exit opening of the source housing. Such a flow guide has been designed as an integral part of an ion source housing to provide for an optimal unidirectional flow past a sampling orifice of a mass spectrometer inlet. Accordingly, the novel design of the present invention prevents recirculation and thus minimizes carryover, chemical noise, and source turbulence and as an added benefit, enables a user to easily clean such a system during maintenance.
