Simultaneous spectrophotometric determination and classical least squares method: a simple experiment to introduce the concept of multivariate calibration
We herein present an experiment where the concentrations of tartrazine, sunset yellow and amaranth in samples containing these three food dyes are determined by system of equations (SE) and classical least squares (CLS) multivariate calibration methods using light absorption data. Firstly, concentra...
