    摘要： A system and method for acquisition of mass spectrometry data is configured to provide a stream of charged particles (e.g., from an analytical volume). A primary mass spectrometer (e.g., time-of-flight mass spectrometer) may be used to separate charged particles of the stream of charged particles based on their mass-to-charge ratio and detect the charged particles in a mass-to-charge spectrum. A stream of precursor ions having a selected mass range may be diverted from the stream of charged particles for fragmentation to provide fragment ions (e.g., fragment ions from the analytical volume). The fragment ions may be provided to a second mass spectrometer for analysis of the fragment ions (e.g., during the same time as the time-of-flight mass spectrometer is separating and detecting charged particles of the stream of charged particles based on their mass-to-charge ratio).
