Publication number: 20220328298Abstract: A device (1) for manipulating charged particles, the device comprising a series of electrodes (2, 3) disposed so as to form a channel for transportation of the charged particles. A power supply unit (5) provides a first supply voltage (7) which changes according to a waveform having a period (T), to axially segmented bunching electrodes (3) to create an electric field within the channel. The potential of the electric field defines a potential well which is translated along the length of the channel such that the potential well is translated a distance substantially equal to its length in an interval of time substantially equal to the period (T). The waveform is substantially continuously smooth throughout its period (T); and, substantially constant in value throughout a finite duration of time (TL<T) within the period (T), corresponding to a minimum of the waveform.Type: ApplicationFiled: August 28, 2020Publication date: October 13, 2022Applicant: SHIMADZU CORPORATIONInventors: Roger GILES, Alina GILES

Publication number: 20220328299Abstract: A device (1) for manipulating charged particles, the device comprising a series of electrodes (2, 3) that form a channel for transportation of the charged particles. A power supply unit (5, 6) provides a voltage to axially segmented bunching electrodes to create a potential well within the channel having one or more local minima between local maxima (50, 51). The well is translated along the channel. An axial extraction region (54) comprises electrodes defining an end of the channel. They receive a supply voltage to create a pseudo-potential within the channel such that the depth of the potential well varies according to the mass-to-charge ratio (m/z) of the charged particles transported therein and reduces as a local maxima of the potential well is translated axially towards the axial extraction region thereby to release the transported charged particles of different mass-to-charge ratio (m/z) at different respective times.Type: ApplicationFiled: August 28, 2020Publication date: October 13, 2022Applicant: SHIMADZU CORPORATIONInventors: Roger GILES, Alina GILES

Patent number: 10770279Abstract: An ion transfer apparatus for transferring ions from an ion source at an ion source pressure, which ion source pressure is greater than 500 mbar, along a path towards a mass analyser at a mass analyser pressure that is lower than the ion source pressure. The apparatus includes a plurality of pressure controlled chambers, wherein each pressure controlled chamber in the ion transfer apparatus includes an ion inlet opening for receiving ions from the ion source on the path and an ion outlet opening for outputting the ions on the path. The plurality of pressure controlled chambers are arranged in succession along the path from an initial pressure controlled chamber to a final pressure controlled chamber, wherein an ion outlet opening of each pressure controlled chamber other than the final pressure controlled chamber is in flow communication with the ion inlet opening of a successive adjacent pressure controlled chamber.Type: GrantFiled: October 20, 2016Date of Patent: September 8, 2020Assignee: SHIMADZU CORPORATIONInventors: Roger Giles, Alina Giles
