Abstract
A method of mass spectrometry is disclosed wherein the intensity of an analyte is determined by determining the intensity of first characteristic fragment ions when the intensity of the first characteristic fragment ions is within a first intensity range corresponding to the detection or unsaturated range of an ion detector. However, when the intensity of the first characteristic fragment ions is outside of the first intensity range so that the ion detector would saturate then the intensity of the analyte is determined by determining the intensity of second different characteristic fragment ions.
