Graphical representation of the MCR bilinear factor decomposition model. a MCR bilinear model of the data matrix, D, obtained in the LC-MS analysis of one single sample. C and ST are the factor matrices which have respectively the concentration (elution) and mass spectra profiles of the MCR resolved components in the analysed sample. b MCR model of the column-wise augmented data matrix, Daug, obtained in the simultaneous analysis of multiple individual, Dk, data matrices, Caug and ST are the factor matrices which have respectively the concentration (elution) profiles of the MCR resolved components in each of the multiple simultaneously analysed samples and the common mass spectra profiles on all of them
