WHITE, GRAY AND BLACK MULTICOMPONENT SYSTEMS - A CLASSIFICATION OF MIXTURE PROBLEMS AND METHODS FOR THEIR QUANTITATIVE-ANALYSIS

Multivariate calibration and resolution methods for handling samples of chemical mixtures are examined from the point of view of the analytical chemist. The methods are classified concordant to three different kinds of analytical mixture systems; i.e. 'white', 'grey', and 'black' analytical systems. Advantages and limitations of available multivariate calibration and resolution methods are discussed with respect to the proposed classification of the analytical mixture problem.
