Figure 1From: An improved independent component analysis model for 3D chromatogram separation and its solution by multi-areas genetic algorithmThe principle of HPLC-DAD dataset. The vector of s i represents chromatogram peaks and the vector of a i represents spectra. The matrix of D i represents 3D dataset containing only one compound, which is formed by a i × s i T . The matrix of X represents the dataset containing more than one compound.Back to article page
