Highest abundance ratio
Webabundance of the ions that reach the detector according to their mass to charge ratio (m/z); the spectrum is often plotted on a relative abundance scale. An example EI MS spectrum is presented in Figure 1. All peak intensities are normalized to the highest peak, in this case the m/z = 31 peak. WebThe intensity of the peak corresponds to the abundance. 84Sr has the smallest peak, which corresponds to its relative abundance of 0.56%, whereas 88Sr has the largest peak, …
