Introduction. Multicomponent spectrometric methods involve the simultaneous determination of compounds in a multicomponent system. These methods have extensively been used for the analysis of drugs in mixtures, pharmaceutical preparations, and clinical samples.

What is multicomponent method of analysis?

In multicomponent systems, specific analytical methods are required to determine the concentrations of individual components in the presence of interfering substances. Ultraviolet and visible spectrometric methods have widely been developed for the analysis of drugs in mixtures and pharmaceutical preparations.

What are the different methods of multicomponent analysis?

These include simultaneous equation method, area under the curve method, two wavelength method, absorbance ratio method, difference & derivative spectrophotometry and orthogonal polynomial method.
