Manipulating Ratio Spectra for the Spectrophotometric Analysis of Diclofenac Sodium and Pantoprazole Sodium in Laboratory Mixtures and Tablet Formulation
Figure 4
(a) Division spectra of 2.0–20.0 μg/mL pantoprazole and (b) division spectra of a standard solution and a mixture solution containing the same concentration of pantoprazole, using 4.0 μg/mL diclofenac as a divisor and methanol as a solvent.
