Abstract
A technique for analyzing ions by determining the time of flight of the ions from a source before detection at a detector. In the technique a series of pulses is generated according to an encoded sequence. Pulses from the series of pulses are selected to launch a plurality of packets of ions from the source, each of the selected pulses launching a packet of ions such that ions launched in the adjacent packets overlap prior to reaching the detector. At the end of the series another cycle of the series is generated again and some of the pulses in the series are selected in the another cycle to launch a plurality of packets of ions from the source. The cycles of pulse generation and selection to launch ions are repeated. The time of arrival of the ions of each packet in the detector is determined to obtain signals corresponding to overlapping spectra of the time of arrival of the packets of ions. The signals are correlated with the encoded sequence to derive a nonoverlapping spectrum from the overlapping spectra.
