Abstract
A mass spectrometer is disclosed wherein ions are passed through an ion mobility separator and are then mass analysed by a Time of Flight mass analyzer. Multiple sets of mass spectral data are obtained which are then post-processed so that mass spectral data relating to ions having undesired charge state(s) is filtered out. The resultant mass spectrum comprises ions having a desired charge state.
