Abstract
A general introduction to multivariate image analysis (MIA) as a useful tool in chemistry is given, by presenting the analysis of two artificial examples. A comparison of a spectrophotometer and a MIA system is described. Similarities between the two systems are discussed and the advantages of both systems are highlighted. In earlier publications, a classification of pure solid substances with MIA using their reflectances was introduced. This paper further develops the method by considering two examples where aqueous solutions of the metal ions, CO 2+, Ni 2+ and Cu 2+, have been investigated. A chemical introduction to the problem and an explanation of the method is given.
