Publication number: 20240003847Abstract: Methods and apparatuses for ion manipulations, including ion trapping, transfer, and mobility separations, using traveling waves (TW) formed by continuous alternating current (AC) are disclosed. An apparatus for ion manipulation includes a surface to which are coupled a first plurality of continuous electrodes and a second plurality of segmented electrodes. The second plurality of segmented electrodes is arranged in longitudinal sets between or adjacent to the first plurality of electrodes. An RF voltage applied to adjacent electrodes of the first plurality of electrodes is phase shifted by approximately 180° to confine ions within the apparatus. An AC voltage waveform applied to adjacent electrodes within a longitudinal set of the second plurality of segmented electrodes is phase shifted on the adjacent electrodes by 1°-359° to move ions longitudinally through the apparatus for separation.Type: ApplicationFiled: September 15, 2023Publication date: January 4, 2024Applicant: Battelle Memorial InstituteInventors: Venkata B.S. Garimella, Ahmed M. Hamid, Yehia M. Ibrahim, Richard D. Smith

Patent number: 11460439Abstract: A system includes, an ion channel extending along a first direction from a first end to a second end. The ion channel is configured to receive ions at the first end of the ion channel. The system further includes a controller configured to apply a first voltage signal to a first plurality of electrodes adjacent to the ion channel. The first plurality of electrodes are configured to generate, based on receipt of the first voltage signal, a first traveling drive potential that travels along the first direction during a separation time. One or more of a travel speed and an amplitude of the first traveling drive potential vary during a first time segment of the separation time.Type: GrantFiled: September 15, 2020Date of Patent: October 4, 2022Assignee: MOBILion Systems, Inc.Inventors: John Daniel DeBord, Ahmed M.

Patent number: 11322340Abstract: Disclosed is an ion carousel having a first surface and a second surface adjacent to the first surface. The second surface includes a first inner array of electrodes arranged along a first loop path and configured to receive a first ion packet and a second ion packet temporally separated from the first ion packet by a separation time. The first inner array of electrodes generates a traveling waveform which includes a plurality of potential wells that travel along the first loop path and receive ions from the first and second ion packets. The plurality of potential wells include at least a first potential well and a second potential well. An output switch is configured to selectively eject ions from the first potential well out of the carousel at time T1 and eject ions from the second potential well out of the carousel at time T2.Type: GrantFiled: August 7, 2020Date of Patent: May 3, 2022Assignee: MOBILion Systems, Inc.Inventors: Ahmed M. Hamid, John Daniel DeBord, Gordon A. Anderson
