Based on the equations of macroscopic electrodynamics, the article considers the most important consequences from the point of view of practical application for condensed matter. It has been theoretically shown that a virtual molecular filter with a fairly high degree of selectivity can be used for them. The theoretical substantiation of mass transfer processes in condensed systems is presented for cases of external influence on them when solving problems of technological change of macroscopic properties of a molecular system. Monitoring problems are indicated when moving the minimum amount of substance in the case of mass transfer for processes: diffusion, adsorption, capillary filtration. The functioning of the filter is based on the theory of macroscopic electrodynamics, namely, on how the space charge density is distributed in the sample under study. The results obtained make it possible to evaluate the physicochemical changes that occur in a condensed medium under external technological influence. The presented theoretical research results can serve as the basis for improving the methods of electrometric monitoring of gaseous and liquid media of unknown qualitative and quantitative composition.
