Manipulating Ratio Spectra for the Spectrophotometric Analysis of Diclofenac Sodium and Pantoprazole Sodium in Laboratory Mixtures and Tablet Formulation
Figure 3
(a) Division spectra of 2.0–24.0 μg/mL diclofenac and (b) division spectra of a standard solution and a mixture solution containing the same concentration of diclofenac, using 4.0 μg/mL pantoprazole as a divisor and methanol as a solvent.
