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

Figure 4

First-derivative double divisor-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. Δ𝜆=5.0 nm. All of the conditions are as Figure 3.
