Secondary Ion Mass Spectrometry Measurements of Isotopic Ratios: Correction for Time Varying Count Rate
Kevin Coakley, A M. Leifer, David S. Simons
In Secondary Ion Mass Spectrometry measurement systems, the count rate of isotopes may vary in time as a particle is consumed during the analysis. Since only one isotope at a time is measured, this drift can introduce systematic error into the estimate of the ratio of any two isotopes. We correct the measurements for drift by aligning the time series of isotopic
