Base Peak

Base Peak

The vertical axis denotes the relative abundance of ions. The most intensive peak in a spectrum is called the "Base Peak", whose intensity is taken as 100 percent. This ion exists most abundantly in the ion source and represents the most stable ion, which is useful for identifying the compound.

In a mass spectrum, the relative intensity of each ion is normally found using the peak with the highest intensity as the "standard" or "base" peak.
