Precise measurement of isotope abundance ratios is usually obtained by a sequential scanning of the appropriate section of the mass spectrum in front of the selection slit of a spectrometer. When secondary ion emission is used, the existence of cluster ions makes it necessary to resort to high mass resolution. So, a precise and reliable peak switching system is required.
