Abstract
Methods of determining isobaric interference during mass analysis in a mass spectrometer are provided. The methods comprise comparing interference-free reaction profiles of a chemical species to reaction profiles of the same chemical species that may comprise isobaric interference, wherein a determination of a difference between the profiles is an indication of isobaric interference being present. Methods of quantifying isobaric interference are also provided, including methods of correcting isotope ratios determined in the presence of isobaric interference.
