ABSOLUTE METHODS IN ANALYTICAL-CHEMISTRY

There is an increasing tendency to obtain the analytical result on the basis of numerical calculations deriving from the theoretical model o f the phenomena responsible for formation of an analytical signal. Suc h procedures where the calculations are based on universal quantities and fundamental physical constants only, may be termed absolute method s. There is a number of terms which refer to methods which do not need direct experimental calibration, which however cannot be named absolu te. This project indicates also existing examples in various analytica l techniques, where the term ''absolute'' is more or less justified.
