Abstract

The capabilities of a photodiode array detector in flow injection analysis for multi-component determination with normal and derivative spectra is outlined. Mixtures of two, three and four components with completely overlapping spectra have been accurately resolved. The effect of wavelength range and mode of spectral selection has also been studied. The proposed analytical method has been successfully applied to the determination of the four active components of a commercial pharmaceutical formulation.
