Tandem mass spectrometry using continuous-wave infrared multiphoton dissociation in an electrostatic linear ion trap

CONCLUSIONS: Fragmentation at the turnaround point of an ELIT by continuous-wave infrared multiphoton dissociation (cw-IRMPD) is demonstrated. In cases where laser power absorption is low and fragmentation occurs over many laps, a mirror-switching pulse may be used to recover varying time-domain signal. The combination of laser activation at the turnaround points and mirror-switching isolation allows for tandem MS in the ELIT.PMID:38356088 | DOI:10.1002/rcm.9698
