Abstract:
1. A method for analyzing mass spectra, the method comprising: detecting signals including signal intensifies in a plurality of spectra, wherein each spectrum in the plurality of spectra comprises data representing signal strength as a function of time-of-flight, mass-to-charge ratio, or a value derived from time-of-flight or mass-to-charge ratio; forming at least one signal cluster by clustering signals with similar times-of-flight, mass-to-charge ratios, or values derived from times-of-flights or mass-to-charge ratios; determining a predetermined number of signals, wherein the predetermined number of signals represents a minimum number of signals for a selected signal cluster; selecting one or more signal clusters from the plurality of signal clusters if the number of signals in a signal cluster meets or exceeds the predetermined number of signals and excluding one or more signal clusters from the plurality of signal clusters if the number of signals in a signal cluster is below the predetermined number of signals; and selecting the times-of-flights, the mass-to-charge ratios, or the values derived from the times-of-flights or the mass-to-charge ratios of the selected one or more signal clusters.
