Abstract

A method of controlling the population of ions in a mass spectrometer in which a first sample of ions is provided in the mass spectrometer, a measure of abundance of a species of interest in the first sample of ions is determined, the measure of abundance comprising an intensity value, and a second sample of ions is introduced into the mass spectrometer. The second sample of ions is introduced in an amount determined at least in part on the measure of abundance of the species of interest in the first sample of ions.
