An Interactive Computer Program for Multicomponent Spectrophotometric Analysis Using Orthogonal Polynomials

Abstract

A generalized interactive computer program (CNVSPI) is presented that enables the analyst to apply several methods for multicomponent analysis using conventional absorbance as well as orthogonal polynomials coefficients. The program performs the following: (i) stores data collected from spectrophotometer, (ii) processes data already stored in a file which include convolution with orthogonal polynomials, solving simultaneous linear equations and applying the least squares principle and (iii) displays data on screen, printer and plotter. Using that program multicomponent spectrophotometric methods have been applied to assay four component mixture in different matrices.
