ABSTRACT
Naturally, developing different methods exerts different inuence on science developing; however, undoubtedly, it is that development of research methods should be permanently paid much attention.
Programming of mobile-phase properties in thin layer chromatography (TLC) naturally, in many cases, inuences substantially the separation of the analyzed mixtures. For example, if the programming of the mobile-phase composition (and of, consequently, its properties) is implemented before a chromatographic plate, there are methods and devices developed for their implementation, which are described in detail in the literature (see, e.g., Refs [2-11]). In the given review, the new variant of TLC with the programming of composition and properties of a mobile phase (MP) is described. The new method of programming is the result of dissolving the active volatile reagent being in the chamber atmosphere and dissolving in the MP migrating on the plate adsorption layer. The active volatile compounds (the modiers) as a result of dissolving in the MP change the properties of the latter in a direction necessary for an experimenter. It is interesting to note that according to the generally accepted opinion, presence of a gas phase in contact with a TLC plate is considered as a negative factor of TLC by most of the researches [2-4]. However, a gas phase
