摘要：

Data from mixtures studied by hyphenated chromatography, e.g., HPLC-DAD and similar techniques, are resolved into spectra and concentration profiles by an iterative technique using elementary matrix transformations. Applications are made to one artificial data set and three sets previously analyzed in the literature. The technique is very fast and seems to perform at least as well as those previously developed, but requires less intervention from the user. (C) 2000 Elsevier Science B.V. All rights reserved.
