Quantitative analysis to assess the amount of paracetamol present in Tachifludec. (a) Weight fractions estimated from powder samples of Tachifludec, where paracetamol has been added at concentrations of 0, 15, 25, 35%(w/w) with three replicates per sample. A linear fit has been carried out on the samples without standard added (samples 0, 1, 2). Insets show the fit of the pure paracetamol profile (red line) on the first (left) and last (right) samples (black line). (b) Calibration plot obtained by the SAM procedure, where a linear fit has been carried out on the samples with the standard added (samples 3–11). Errors are calculated from the whole-profile fitting procedure on single mixtures, and regression lines are superimposed in red.
