(a) Plot of the nominal concentrations of the seven dilutions of dipyrone, in the range from 400 to 600 mg/mL (80 to 120%) versus the intensities of PC1, showing high correlation of the PCR model (). (b) Plot of the model-estimated concentrations versus the nominal concentrations and estimated (1.3%).
