ABSTRACT:
A mass spectral analyzer system providing automated discovery, deconvolution and identification of mass spectrum is taught. Conventionally acquired mass data files are re-sorted from chronological to primarily ion-mass order and secondarily to chronological order within each ion-mass grouping. For each ion-mass measured, local peaks or maximums are identified through an integrator means. All local maximums are then sorted and partitioned such that a set of deconvoluted spectra is obtained such that each element of the set constitutes an identifiable compound. Compounds are then matched to reference spectra in library datafiles by conventional probabilistic matching routines.
