摘要
Spectroscopic analyses of complex mixtures within the matrix of a sample can oftentimes be complicated by spectral overlap of the constituents and/or the matrix, making it difficult to quantitatively assay each constituent therein. Methods for analyzing a sample can comprise: providing a sample comprising a matrix and one or more constituents therein; exposing the sample to electromagnetic radiation in a spectral region where the matrix optically interacts with the electromagnetic radiation, so as to acquire a spectrum of the matrix; and analyzing the spectrum of the matrix within a wavelength range where the matrix has a molar extinction coefficient of at least about 0.01 M-1mm-1 to determine at least one property of the sample, the at least one property of the sample being selected from the group consisting of a concentration of at least one constituent in the sample, at least one characteristic of the sample, and any combination thereof.
