The Linear Combination of Spectrophotometry of Multi-Wavelength Data and Its Applications

Abstract

Abstract: The linear combination of multi-wavelength data (absorbance) is developed as a new computational spectrophotometry to improve the selectivity and accuracy, based on the combination of simultaneous equations with a set of proper coefficients. The absorbance obtained is in proportion to the concentration of the analyzed compounds and independent of the interferents, thus the in terference can be removed. The proposed method, which has the advantage for determining multi-wavelength data with simpler computation and can be used in single or simultaneous measurement, has been applied to the analysis of compound pharmaceutical preparations.

Key words: Linear combination of multi-wavelength data, Computational photometry, Selectivity, Compound pharmaceutical analysis
