mass spectrum

n.
A pattern of charged atoms, molecules, or isotopes formed when a mass spectroscope distributes them by mass and records them electronically or photographically as a spectrum.

Strictly, mass spectrums report "m/Z," mass divided by charge, which corrects for this; and in our pattern matching type application, this proportion of fragments with multiple charges just adds additional spectral peaks which form part of the overall pattern.
Note that the individual peaks in a mass spectrum are not some Gaussian curve shape as in most techniques, but exact mass value lines, and that the instrument resolution can be sufficient to differentiate even isotopic differences.
Well, it turns out that if we use a relatively uniform sample of bacteria such as a single colony from a microbiological media plate as a target, we get a very complex mass spectrum pattern out of our MALDI-TOF.
