Intensity relative to base peak (in mass spectrometry)
intensity relative to base peak (in mass spectrometry)

relative intensity (in mass spectrometry)

Ratio of intensity of a resolved peak to the intensity of the resolved peak that has the greatest intensity (base peak). This ratio is generally measured as the normalized ratio of the heights of the respective peaks in the mass spectrum, with the height of the base peak taken as 100.

Note: Intensity is a measure of detector response and should not be used to describe the abundance of ions.

GOLD BOOK DEFINITION

Intensity relative to base peak (in mass spectrometry)

http://goldbook.iupac.org/I03073.html

The ratio of intensity of a separated ion beam to the intensity of the separated ion beam which has the greatest intensity. This ratio is generally equated to the normalized ratio of the heights of the respective peaks in the mass spectrum, with the height of the base peak being taken as 100.
