The Spectrophotometric Multicomponent Analysis of a Ternary Mixture of Paracetamol, Aspirin, and Caffeine by the Double Divisor-Ratio Spectra Derivative Method

Figure 3

Double divisor of the ratio spectra for a ternary mixture of aspirin, caffeine, and paracetamol after simultaneous standard addition of three components in the concentration range of 10–60 μmol L−1 (1–6). Double divisors concentrations are CAF, 2.0 μmol L−1 + PAR, 2.0 μmol L−1. All of the conditions are as Figure 2.
