METHOD FOR ANALYZING MIXTURE COMPONENTS
5
The present invention relates to a method for analyzing mixture components, comprising: (1)
separating a mixture sample by using chromatographic technology, to obtain a preliminary
chromatogram; (2) sampling as required any one interval in the preliminary chromatogram obtained
in step
(1), to obtain a series of spectrograms in different retention times, which are referred to as
compound spectrograms; (3) performing calculation, by using a series of methods of an entropy
10
minimum algorithm, in the mixture spectrograms obtained in step (2), to obtain each reconstructed
pure spectrum and a corresponding pseudo concentration thereof. The method combines the
chromatographic technology and the entropy minimum algorithm, and overcomes dependence on
component
separation in an existing analysis method, making separation not important any more.
There is no need to completely separate each component in the mixture. Meanwhile, a prerequisite
15
for using the entropy minimum algorithm is met. The method is universal, fast, and highly efficient,
requires low costs, does not have high requirements on personnel, and has a great application
prospect.
