如果含有元素的多个同位素的质量选择离子由于失去含有该元素的中性而碎裂，则产物离子将被观察为多个峰。这种峰的“同位素簇”，虽然与正常质谱中发现的峰的外观不同，但也表明了前体离子的同位素组成。
If a mass selected ion containing multiple isotopes of an element fragments by loss of a neutral containing the element, the product ions will be observed as multiple peaks. This ‘isotopic cluster’ of peaks, although of a different appearance than those found in normal mass spectra, also indicates the isotopic composition of the precursor ion.
