Abstract:
The principles of stoichiog. and novel ref.-free methods of mol. and phase anal. for complex unknown mixts. are considered. The stoichiog. can be inferred from stoichiometry of mass transfer of unsteady homo- and heterophase processes and joins both operations: sepn. of mixt. by chromatog., electromigration, dissoln. or others and detn. of stoichiometry of a substance flow with time. The stoichiog. allows a chem. compd. to be detd. by its primary property, namely, by stoichiometry of elemental compn. Stoichiograms provided a basis for such type of information. They are time variances of molar ratio for mass transfer rates of chem. elements from multielement substances. Invariancy to concn. and temp. of solvents, hydrodynamic regime is a fundamental property of the stoichiograms in the case of individual compds. Therefore the stoichiograms are kept const. and are equal to formula stoichiometric coeffs. of the individual compd. Therefore the stoichiograms are kept const. and are equal to formula stoichiometric coeffs. of the individual compd. Theory and methodol. of new stoichiog. methods, differential dissoln. and ion-chromato-stoichiog. are presented. New equipment, stoichiograph, and a new procedure of differential dissoln., stoichiog. titrn., are discussed here in details. Applications of differential dissoln. to analyze multielement and polyphase cryst. and amorphous samples are given.
