Patent number: 10466202Abstract: Methods and apparatuses for ion peak compression and increasing resolution of ions are disclosed. Packets of ions are introduced into a device. A first electric field is applied for dispersing the ion packets temporally or spatially according to their mobilities. A second intermittent traveling wave is applied for regrouping or merging the dispersed ion packets into a lesser number of trapping regions with narrower peaks. The ions packets are compressed into the narrower peak regions by varying a duty cycle of the intermittent traveling wave.Type: GrantFiled: July 3, 2018Date of Patent: November 5, 2019Assignee: Battelle Memorial InstituteInventors: Yehia M. Ibrahim, Sandilya Garimella, Richard D. Smith
