Patent number: 11527395Abstract: A method of introducing and ejecting ions from an ion entry/exit device (4) is disclosed. The ion entry/exit device (4) has at least two arrays of electrodes (20,22). The device is operated in a first mode wherein DC potentials are successively applied to successive electrodes of at least one of the electrode arrays ((20,22) in a first direction such that a potential barrier moves along the at least one array in the first direction and drives ions into and/or out of the device in the first direction. The device is also operated in a second mode, wherein DC potentials are successively applied to successive electrodes of at least one of the electrode arrays (20,22) in a second, different direction such that a potential barrier moves along the array in the second direction and drives ions into and/or out of the device in the second direction.

Publication number: 20220359177Abstract: Disclosed herein are various methods and apparatus for performing charge detection mass spectrometry (CDMS). In particular, techniques are disclosed for monitoring a detector signal from a CDMS device to determine how many ions are present in the ion trap (10) of the CDMS device. For example, if no ions are present the measurement can then be terminated early. Similarly, if more than one ion is present, the measurement can be terminated early, or ions can be removed from the trap (10) until only a single ion remains. Techniques are also provided for increasing the probability of there being a single ion in the trap (10). A technique for attenuating an ion beam is also provided.Type: ApplicationFiled: May 16, 2022Publication date: November 10, 2022Applicant: Micromass UK LimitedInventors: Keith Richardson, Jeffery Mark Brown, David J.

Publication number: 20220341896Abstract: The present disclosure discusses a method of separating a sample of tyrosine kinase inhibitors or metabolites of tyrosine kinase inhibitors which includes injecting the sample into the chromatographic system having one or more low-bind coated surfaces along the flow path; flowing the sample through the chromatographic system; separating the sample; and analyzing the separated sample. Consequently, the sample does not bind to the low-binding surface coatings (e.g., alkylsilyl coatings) of the flow path. The applied coating can reduce peak tailing and decrease carryover for tyrosine kinase inhibitor samples during chromatographic analysis.Type: ApplicationFiled: April 27, 2022Publication date: October 27, 2022Applicant: Micromass UK LimitedInventors: Stephen Balloch, Lisa Jane Calton, Gareth Hammond
