Publication number: 20150228467Abstract: An ion guide for mass spectrometry comprising an electrode arrangement of at least two electrodes, at least one of which is an RF electrode, arranged adjacent to each other but spaced apart on a planar surface of a dielectric material and arranged at a distance from an ion flow path, wherein a portion of the dielectric surface is exposed between an adjacent pair of the spaced apart electrodes and wherein at least one electrode of said adjacent pair of electrodes is arranged to overhang the exposed portion of surface between them such that there is no direct line of sight from the ion flow path to the exposed portion of dielectric surface. The device enables RF guiding of ions accompanied by much reduced charging-up of dielectric surfaces and reduced amount of collisions of neutral species with electrodes.Type: ApplicationFiled: September 19, 2013Publication date: August 13, 2015Inventors: Dmitry Grinfeld, Jan-Peter Hauschild, Wilko Balschun, Eduard Denisov, Alexander Makarov

Patent number: 8841604Abstract: A mass analyzer comprises: an electrical field generator, providing a time-varying electric field for injection of ions to be analyzed, excitation of ions to be analyzed or both; first and second detection electrodes, each of which receives a respective voltage pickup due to the time-varying electric field and provides a respective detection signal based on a respective image current at the detection electrode; and a differential amplifier, providing an output based on the difference between the detection signal for the first detection electrode and the detection signal for the second detection electrode. It may also be provided that the electrical field generator comprises at least one field generating electrode without a spatially symmetrical counterpart and the capacitance between each field generating electrode and the first detection electrode is substantially the same as the capacitance between that field generating electrode and the second detection electrode.Type: GrantFiled: May 14, 2012Date of Patent: September 23, 2014Assignee: Thermo Fisher Scientific (Bremen) GmbHInventors: Eduard V.

Publication number: 20140224975Abstract: Disclosed herein is a mass spectrometry method having steps of: transmitting ions from an ion source through a mass filter; processing ions received from the mass filter in a discontinuous ion optical device downstream of the mass filter; operating the mass filter for a plurality of periods in a mass/charge ratio (m/z) filtering mode to transmit ions in one or more selected ranges of m/z to the discontinuous ion optical device; and operating the mass filter in a broad mass range mode transmitting ions of a mass range substantially wider than any mass range transmitted in the m/z filtering mode during one or more periods in which the discontinuous ion optical device is not processing ions from the mass filter. Utilization of this method assists to reduce contamination in the mass filter.Type: ApplicationFiled: February 13, 2014Publication date: August 14, 2014Applicant: Thermo Fisher Scientific (Bremen) GmbHInventors: Andreas Kuehn, Jan-Peter Hauschild, Dirk Nolting, Oliver Lange, Eugen Damoc
