Patent number: 9768003Abstract: A method of configuring a Faraday detector in a mass spectrometer is described. The mass spectrometer defines a central ion beam axis, and the Faraday detector is moveable relative to the central ion beam axis. The Faraday detector includes a detector arrangement having a detector surface, and a Faraday slit defining an entrance for ions into the detector arrangement. The Faraday detector has an axis of elongation which extends through the Faraday slit. A width of the Faraday slit is chosen, and the angle between the axis of elongation of the Faraday detector and the central ion beam axis is adjusted such that ions striking the detector surface do not generate secondary electrons.Type: GrantFiled: August 12, 2016Date of Patent: September 19, 2017Assignee: Thermo Fisher Scientific (Bremen) GmbHInventors: Michael Deerberg, Michael Krummen, Ronald Seedorf, Silke Seedorf

Patent number: 9754775Abstract: A magnetic adjustment mechanism 100 comprising a chamber 10, an element 12 pivotally mounted within the chamber 10 and comprising a magnetic portion 14, and a magnetic actuator 18 arranged outside the chamber 10 to allow magnetic coupling with the magnetic portion 14 of the element 12 such that movement of the magnetic actuator 18 causes an adjustment of the position of the element 12. The adjustment mechanism 100 may be used within a vacuum chamber of a mass spectrometer to control the position of a moveable element from outside the chamber.Type: GrantFiled: December 8, 2015Date of Patent: September 5, 2017Assignee: Thermo Fisher Scientific (Bremen) GmbHInventors: Silke Seedorf, Michael Krummen

Patent number: 7211794Abstract: An improved FT-ICR Mass Spectrometer has an ion source 10 which generates ions that are transmitted through a series of multipoles 20 to an ion trap 30. Ions are ejected from the trap 30, through a series of lens and multipolar ion guide stages 40–90, and into a measurement cell 100 via an exit/gate lens 110. The measurement cell is mounted in a vacuum chamber 240 and this assembly is slideably moveable into a bore of a superconducting magnet 400 which provides the magnetic filed to cause cyclotron motion of the generated ions in the cell 100. By minimising the distance between the source 10 and cell 100, and by careful alignment of the ion optics, the ions can travel at high energies right up to the front of the measurement cell 100. The cell 100 extends in the longitudinal direction of the magnet bore and is coaxial with that. The ratio of the sectional area of the magnet bore to the sectional area of the cell volume is small (less than 3).Type: GrantFiled: March 9, 2004Date of Patent: May 1, 2007Assignee: Thermo Finnigan LLCInventors: Robert Malek, Kai Jurgen Meyer, Silke Seedorf, Stevan Roy Horning
