Abstract: Amodified matrix approach to multicomponent spectroscopic analysis has been described. This matrix is used for simultaneous determination of Aspirin, Phenacetin, and Caffeine with the ultraviolet spectrophotometry. Calibration with standard mixtures incorporates molecular interactions and nonzero intercept in the analysis matrix. This method, the Linear Programming, and the Coordinate Rotation are compared and discussed.
