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 ... WebThe duty cycle for recording each mass in the spectrum is generally poor, and the higher the resolution or the wider the mass range the poorer the duty cycle. An array detector allows simultaneous acquisition over a range of masses thereby improving the duty cycle when used to record a spectrum. reactivate utr number onlineWebThe duty cycle is not a constant for an instrument design but is a mass-dependent function and is least for smaller masses.
