Abstract: A data acquisition system for a TOF mass spectrometer comprises a processing module and a data collection module. The processing module generates a stream of data comprising, for each respective transient of a first scan, a set of time-intensity related parameter pairs. For each new set of data, the data collection module reads out a previous set of data from a previous memory bank, merges that previous set of data with the new set of data, and writes that latest merged set of data into a memory bank other than the previous memory bank. The data acquisition system provides a convenient way to merge sequential sets of time-intensity related parameter pairs for respective transients as a stream of data for a first scan is generated.
