INTELLIGENT TARGET-BASED ACQUISITION
A method of mass spectrometry comprises ionizing a sample eluting from a separation device in order to generate a plurality of parent ions. The method further comprises generating a target list of ions, which includes a predicted mass to charge ratio, a predicted chromatographic retention or elution...

| description | A method of mass spectrometry comprises ionizing a sample eluting from a separation device in order to generate a plurality of parent ions. The method further comprises generating a target list of ions, which includes a predicted mass to charge ratio, a predicted chromatographic retention or elution time, and a predicted ion mobility drift time, derived from a model. Multiple cycles of operation are then performed as the sample elutes from the separation device. Each cycle of operation includes mass filtering the parent ions so that selected ions having mass to charge ratios within a first mass to charge ratio range are onwardly transmitted to a fragmentation or reaction device. The target list is then checked and the model is updated accordingly. The first mass to charge ratio range can then be adjusted in response to the updated model. |
