Abstract: A method of analysing a sample mass spectrum comprises comparing a sample mass spectrum of a sample with each reference mass spectrum of plural reference mass spectra. A similarity index is assigned to each reference mass spectrum of the plural reference mass spectra based on similarity between the sample mass spectrum and the reference mass spectrum. For each group of one or more groups of the plural reference mass spectra, the similarity indexes for the reference mass spectra belonging to the group are combined so as to provide a group index for the group at a first level of a hierarchy of sample characteristics. The reference mass spectra belonging to each group are mass spectra of reference samples that have a particular characteristic in common. The method provides a way to categorise a sample as belonging to a particular group of reference samples.

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.
