DEVELOPMENT OF THE APPLICATION OF INFORMATION-THEORY IN ANALYTICAL-CHEMISTRY

Information theory has had a long period of development, it has well established terminology and terms. Basically the theory started from Shannon's work on the decrease of entropy, applies the Kerridge-Bongard mass and the divergence criterion according to Kullback. As in actual analytical applications real standard deviations are available, sigma values are to be transformed into s values at a pre-determined significance level alpha and degree of freedom F. In analytical procedures the so called ''real values'' can be determined, thus the effect of these parameters on the information contents can be taken into consideration. Finally, the masses of the information contents in multielement determinations are defined so that the cross correlations between the elements determined can be taken into consideration.
