Duty cycle mass spectrometry
WebFeb 1, 2024 · Though more complete ejection of the accumulated ions was reported when using helium, the IMS duty cycle (1.6–33%) was still far from 100% since the capacity of the ion funnel/trap was not sufficient to store ions for the entire duration of the 60 ms drift time. Introduced in 2011 by Park and coworkers, trapped ion mobility spectrometry (TIMS ... WebAug 17, 2007 · The duty cycle is not a constant for an instrument design but is a mass-dependent function and is least for smaller masses. The method described here is …
