Patent number: 11887832Abstract: An isotope ratio mass spectrometer has an ion source, a static field mass filter, a reaction cell to induce a mass shift reaction, and a sector field mass analyser for spatially separating ions from the reaction cell according to their m/z. A detector platform detects a plurality of different ion species separated by the sector field mass analyser. The static field mass filter has a first Wien filter that deflects ions away from a longitudinal symmetry axis of the spectrometer in accordance with the ions' m/z, and a second Wien filter that deflects ions back towards the longitudinal symmetry axis in accordance with the ions' m/z. An inverting lens is positioned along the longitudinal axis between the Wien filters to invert the direction of deflection of the ions from the first Wien filter. The static field mass filter provides high transmission and improved spectrometer sensitivity. The first and second Wien filters permit simple tuning.Type: GrantFiled: March 24, 2022Date of Patent: January 30, 2024Assignee: Thermo Fisher Scientific (Bremen) GmbHInventors: Johannes Schwieters, Gerhard Jung

Publication number: 20230343571Abstract: An ion optical arrangement (1) for use in a mass spectrometer comprises electrodes (11, 12, 14) comprising a multipole arrangement defining an ion optical axis, and a voltage source for providing voltages to the electrodes to produce electric fields. The ion optical arrangement is configured for producing a radio frequency electric focusing field for focusing ions on the ion optical axis. The radio frequency electric focusing field has a varying frequency so as to reduce any mass dependence of ion trajectories through the ion optical arrangement. The ion optical arrangement may further he configured for producing a static electric field in response to a DC bias voltage applied to the multipole arrangement. A superimposed varying electric field may be produced by superimposing an AC voltage upon the DC bias voltage.Type: ApplicationFiled: June 22, 2023Publication date: October 26, 2023Applicant: Thermo Fisher Scientific (Bremen) GmbHInventors: Henning WEHRS, Johannes SCHWIETERS, Gerhard JUNG

Patent number: 10748755Abstract: An electrostatic trap such as an orbitrap is disclosed, with an electrode structure. An electrostatic trapping field of the form U?(r, ?, z) is generated to trap ions within the trap so that they undergo isochronous oscillations. The trapping field U?(r, ?, z) is the result of a perturbation W to an ideal field U(r, ?, z) which, for example, is hyperlogarithmic in the case of an orbitrap. The perturbation W may be introduced in various ways, such as by distorting the geometry of the trap so that it no longer follows an equipotential of the ideal field U(r, ?, z), or by adding a distortion field (either electric or magnetic). The magnitude of the perturbation is such that at least some of the trapped ions have an absolute phase spread of more than zero but less than 2? radians over an ion detection period Tm.Type: GrantFiled: January 30, 2019Date of Patent: August 18, 2020Assignee: Thermo Fisher Scientific (Bremen) GmbHInventors: Alexander A.

Publication number: 20160027633Abstract: Mass spectrometer collision/reaction cell multipole and method. The multipole may have first and second portions and an intermediate portion therebetween, the first and second portions operating at first and second q values lower than a third q value at the intermediate portion. A low-mass cut-off of the multipole may be controlled by varying a q value from a first to at least a second value. The multipole may have multipole electrodes disposed about a central axis and having a respective first portion, second portion, and intermediate portion therebetween which is radially closer to the central axis. This offers relatively high acceptance and ion transmission, while providing low-mass cut-off for removing undesired/interfering ions and helping reduce background count.Type: ApplicationFiled: July 28, 2015Publication date: January 28, 2016Inventors: Gerhard JUNG, Lothar ROTTMANN
