Claim:
1. A mass spectrometer, comprising: an ion source of the type being configured to continuously generate ions from a sample being supplied thereto, a trapped ion mobility separator (TIMS) being configured to receive the generated ions in accumulated volumes thereof, and further being configured to output these accumulated volumes in short pulses of ion species that have been separated in time by their ion mobility, the trapped ion mobility separator being configured to use parallel ion accumulation (PATIMS), wherein ions are accumulated in an accumulation unit separated by their ion mobility while scanning the ions according to their ion mobility in a subsequent scanning unit, and the ions are transferred, after each scan, from the accumulation unit to the scanning unit, a first mass filter being configured to receive the ion species and select precursor ions therefrom to be fragmented, a fragmentation cell being configured to receive and fragment the selected precursor ions, a second mass filter being configured to receive and select fragment ions resulting from the precursor ions by the fragmentation, and an ion detector being configured to receive and measure an ionic output from the second mass filter.
