Patent number: 11342175Abstract: A mass spectrometer comprising: a multi-reflecting time of flight (MRTOF) mass analyser or mass separator having two gridless ion mirrors 2 that are elongated in a first dimension (Z-dimension) and configured to reflect ions multiple times in a second orthogonal dimension (X-dimension) as the ions travel in the first dimension; the spectrometer configured to operate in: (i) a first mode for ions having a first rate of interaction with background gas molecules in the mass analyser or separator, such that the ions are reflected a first number of times between the ion mirrors 2; and (ii) a second mode for ions having a second, higher rate of interaction with background gas molecules in the mass analyser or separator, such that ions are reflected a second, lower number of times between the ion mirrors 2.Type: GrantFiled: May 3, 2019Date of Patent: May 24, 2022Assignee: Micromass UK LimitedInventors: Jeffery Mark Brown, Boris Kozlov

Publication number: 20220148867Abstract: A method of self-calibrating a mass spectrometer or mass spectral data is disclosed. At least some first observed mass to charge ratios are matched with or against a comprehensive reference set of possible or predicted elemental compositions having known precise mass to charge ratios. One or more calibration parameters of a calibration routine are then adjusted so as to optimise the match between one or more of the first observed mass to charge ratios and the corresponding known precise mass to charge ratios of one or more possible or predicted elemental compositions contained within the reference set.Type: ApplicationFiled: March 2, 2020Publication date: May 12, 2022Applicant: Micromass UK LimitedInventors: Boris Kozlov, Vasiliy Makarov, Keith Richardson

Patent number: 11114291Abstract: A method of filtering ions (16) is disclosed comprising: providing an ion filter (6) having an ion entrance, an ion exit and a plurality of electrodes (18); applying an AC and/or RF voltage to at least a first electrode so as to generate a pseudo-potential barrier; and urging ions towards the pseudo-potential barrier as they travel from the entrance to the exit whilst maintaining the ion filter (6) at a pressure such that first ions are repelled by the pseudo-potential barrier and so are transmitted through the filter to said exit, whereas second ions having substantially the same mass to charge ratio as the first ions but a lower mass are not capable of being repelled by the pseudo-potential barrier and reaching said exit.Type: GrantFiled: January 23, 2018Date of Patent: September 7, 2021Assignee: MICROMASS UK LIMITEDInventors: Boris Kozlov, David J. Langridge
