Pulsed q dissociation
A process that involves precursor ion activation at high Q, a time delay to allow the precursor to fragment, then a rapid pulse to low Q where all fragment ions are trapped. The product ions can then be scanned out of the ion trap and detected. [database_cross_reference: PSI:MS]
