Abstract

A method is proposed whereby pigments content (in a two or more components admixture) can be determined accurately and directly from the spectra, thus dispensing the time consuming initial step of pigments separation. The procedure is based upon a nonlinear curve fitting of the visible spectrum of the pigments with a predicted function of the individual dyes. The logarithmic normal distribution function showed a remarkable fitting with the pigments tested (Amaranth‐Red # 2, Tartrazine‐Yellow # 5 and Yellow 2G) thus, used as the mathematical model for the curve fitting process.
