DEVELOPMENT OF THE APPLICATION OF INFORMA TION-THEORY IN ANALYTICAL-CHEMISTRY

Information theory has had a long period of development, it has well e stablished terminology and terms. Basically the theory started from Sh annon'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 signifi cance level alpha and degree of freedom F. In analytical procedures th e so called ''real values'' can be determined, thus the effect of thes e parameters on the information contents can be taken into considerati on. Finally, the masses of the information contents in multielement de terminations are defined so that the cross correlations between the el ements determined can be taken into consideration.
