USE OF THE SPECTRAL TRACE LENGTH IN DETERMINING THE CONCENTRATION OF KNOWN COMPOUNDS IN COMPLEX-MIXTURES

The principal of minimum length of a spectral trace has been used to d etermine the concentration of a known compound in a mixture of other u nknown compounds when the unknown compounds are not available for stud y without the known compound mixed in with them. This method works whe re the spectrum of the unknown compounds approximates a quadratic curv e and does not have spectral peaks in a region where there are spectra l peaks of the known compound.
