Figure 6. Calculated percentage of propyl (green, closed circles) and butyl (black, open circles) salicylate in PS:BS binary mixtures determined from GC–FID peak area vs. known PS gravimetric weight percentage. The R2 value of 0.9984 indicates a strong degree of correlation between the chromatographic- and mass-derived values.
