8.1.4 Isotope Peaks as a Criterion For Signal Integrity

Isotope peaks are so important that in this laboratory, we consider their presence a requirement for the validity of a mass peak. A peak will be rejected as valid data if it lacks an isotope peak, provided it corresponds to a structure composed of atoms with more than one common isotope. Not all mass spectrometry labs use this criterion.
