Abstract:
1. A method of blind extraction of more pure components than mixtures in 1D and 2D NMR spectroscopy and mass spectroscopy by combined use of sparse component analysis and detection of single component points, comprising the following steps: recording two or more mixtures data X using a mixtures sensing device wherein a recording domain of the mixture data is defined by equation [I]: where S is an unknown matrix of pure components and A is an unknown mixing or concentration matrix, storing the recorded two or more mixtures data in a data storing device, executing instructions on a processor of an instruction executing computer for: provided that mixtures data X [I] are 1D or 2D NMR spectroscopy data, and pure components in the wavelet representation domain defined by equation [II] are sparser than in recording domain defined by equation [I], provided that mixtures data X [I] are mass spectrometry data, where H(X) represents Hilbert transform of X and j=√{square root over (−1)} represents imaginary unit, where Δθ is some predefined angular displacement, outputting output data including an identification of the estimated pure components to an output device for displaying or storing output data.
