Figure 4. Calculated percentage of methyl (red, closed circles) and ethyl (blue, open circles) salicylate in MS:ES binary mixtures determined from GC–FID peak area vs. known MS gravimetric weight percentage. The R2 value of 0.99996 indicates a strong degree of correlation between the chromatographic- and mass-derived values.
