摘要: A spectrometer for identifying a mixture is provided. The spectrometer includes a detector configured to generate a signal based on an interaction of light with a sample of the mixture, and a memory device having a library and a correlation matrix stored therein, wherein the library includes a plurality of spectra, each spectrum associated with a respective compound, and wherein the correlation matrix includes a correlation between each possible pair of spectra in the library. The spectrometer further includes a processor coupled to the memory device and configured to determine a spectrum of the mixture based on the signal generated by the detector, calculate a correlation vector that includes a correlation between the mixture spectrum and each spectrum in the library, and identify the mixture based on the correlation matrix and the correlation vector.

摘要: Methods, systems and computer program products for identifying components of an unknown mixture using spectral analysis techniques. The method includes comparing the spectrum of the unknown mixture with the spectra of library compounds to obtain candidate mixture combinations. A model is generated for each of the candidate mixture combinations based on a modeling metric. A residual spectrum is computed corresponding to each of the candidate mixture combinations by removing the spectrum of each of the compounds of the candidate mixture combination from the spectrum of the unknown mixture. One or more potential compounds are identified by comparing the residual spectrum with the spectrum of library compounds. The potential compounds are added to the candidate mixture combinations to generate an updated list of the candidate mixture combinations. The search algorithm repeats the steps described above on the updated candidate mixture combinations, until a first termination condition is satisfied.
