摘要
A method of mass spectrometry comprises ionising a sample eluting from a separation device in order to generate a plurality of parent ions. Multiple cycles of operation are performed as the sample elutes from the separation device. Each cycle of operation comprises mass analysing the parent ions to obtain parent ion mass spectral data, and mass analysing fragment or product ions derived from the parent ion to obtain fragment or product ion mass spectral data. Each cycle of operation also comprises mass analysing fragment or product ions derived from parent ions having mass to charge ratios within a first range to obtain first fragment or product ion mass spectral data, and mass analysing fragment or product ions derived from parent ions having mass to charge ratios within a second different range to obtain second fragment or product ion mass spectral data. The method can provide a hybrid data independent acquisition (DIA) and data dependent acquisition (DDA) approach.
