relative abundance

A term defined in the context of mass spectrometry as the measured intensity of an ion beam at the designated m/z value.

Relative abundance refers to the practice of assigning to the most abundant ion in a measured and plotted mass spectrum a relative abundance of 100% and normalising all other ion abundances to that value. To be precise, ion beams are measured in intensity, and ions in abundance.
