Deisotoping. A contrived example of deistoping. The same molecule is displayed here in three reduced isotopic envelopes (denoted by color) created from single- ([M + H]⁺¹), double- ([M + H]⁺²) and triple-charged ([M + H]⁺³) instances of the molecule. The monoisotope (the lowest m/z ion) from each isotopic envelope is combined to form the deistoped monoisotopic peak.
