The massspectrum of the daughter ions is recorded by sequentially ejecting the product ions with a mass-selective instability scan. If we seek to identify background phenomena responsible for the seed massspectrum differences, the following effects should be considered. Tentative compound identifications were performed according to the massspectrum library and correspond to the best fits to known mass spectra (fit factors > 90%). The massspectrum reflected ions corresponding to the molecular weights of the oligomers which were expected to be produced from the mixture of alkylamino acids. The detector also records the relative abundance, which is plotted against the m/z value to give the massspectrum. Complicated ions were observed in the massspectrum. The different amounts of extension products resulting from the nonmutant (filled peak) and mutant (open peak) alleles are reflected in the massspectrum by their different peak heights. This notation is not uncommon in the physics of mass spectrometry but is rarely used as the abscissa of a massspectrum.

A typical massspectrum shows multiple signals because the molecular ion fragments into a complex mixture of ions and uncharged radical species.

The second problem is that the massspectrum from a complex mixture is very difficult to interpret because of the overwhelming number of mixture components. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A massspectrum (plural "spectra") is a plot of the ion signal as a function of the mass-to-charge ratio.

The mass spectrometer then isolates ions of a particular peptide, subjects them to collision-induced dissociation, and records the produced fragments in a tandem massspectrum. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This is because the massspectrum includes cluster ions as well as elemental ions. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Many reaction pathways exist for fragmentation, but only newly formed cations will show up in the massspectrum, not radical fragments or neutral fragments. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A massspectrum is an intensity vs. "m/z" (mass-to-charge ratio) plot representing a chemical analysis. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Since unique elements have characteristic (signature) spectras, atomic spectroscopy, specifically the electromagnetic spectrum or massspectrum, is applied for determination of elemental compositions. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A notation has been developed for indicating peptide fragments that arise from a tandem massspectrum.
