Abstract
A dual analyser mass spectrometer obtains MS1/MS2 scans of positive and negative ions by: operating an ion source and processing region at a first polarity; performing, by a first mass analyser (FMA) at the first polarity, MS1 or MS2 scan(s); switching polarity of the FMA to a second polarity; performing, by a second mass analyser (SMA) at the first polarity, MS1 or MS2 scan(s), wherein at least part of the MS1 or MS2 scan(s) performed by the SMA is performed while the FMA is switching polarity. Alternatively, the FMA may be operated at a first polarity and the SMA at a second polarity opposite to the first, and after initiating at least one MS1 scan and/or MS2 scan by the FMA, switching the polarity of the source and ion processing region to a second polarity and performing at least one MS1 scan and/or MS2 scan with the SMA.
