Abstract

An uncertainty weighted average of the equalized amounts of two or more quantifier ions is calculated from a quantitation experiment itself. n known i ions of a compound are mass analyzed over time in each of m different samples, producing n XIC peaks for each of the m samples. A reference ion j is selected that is a j ion of the n i ions or a hypothetical ion j. A ratio r(j,i) of a peak area of the j ion to a peak area of each ion of the n i ions is calculated for each of the m samples, producing m r(j,i) ratios for each of the n i ions. An expected ratio r(j,i) is calculated for each ion of the n i ions from the m r(j,i) ratios for each of the n i ions. For each sample, the uncertainty weighted average is calculated using r(j,i).
