Paper Abstract

Several methods can be used to resolved overlapped bands in the spectra of mixtures. For most of these methods an estimate of the number of components in the mixture must be made as the first step. The number of components can sometimes be deduced using factor analysis or the absorbance ratio technique, but the answers given by these techniques are often ambiguous. When the number of components is known, the spectrum of each individual component may be obtained using absorbance subtraction routines; however, for this technique to be successful the spectroscopist should have some knowledge of the composition of his sample, and he needs the spectra of at least as many samples of different composition as there are components in the mixture. The problem of mixture analysis is therefore often reduced to the problem of estimating the number of components present in the sample.
