Abstract
The resolution of a TOF mass analyzer is maintained despite a loss of resolution in one or more channels of a multichannel ion detection system by selecting the highest resolution channels for qualitative analysis. Ion packets that impact a multichannel detector are converted into multiplied electrons and emitted from two or more segmented electrodes that correspond to impacts in different regions across a length of the detector. The electrons received by each electrode of the two or more segmented electrodes for each ion packet are converted into digital values in a channel of a multichannel digitizer, producing digital values for at least two or more channels. Qualitative information about the ion packets is calculated using digital values of a predetermined subset of one or more channels of the at least two or more channels known to provide the highest resolution.
