Principal predestinations of different kinds of chromatography and related (hyphenated) separation methods are identification of analytes in multicomponent samples by non-spectroscopic methods and their quantitation. The first problem is solved using retention parameters of analytes, while the second is based on processing their peak areas. However, the search for new approaches remains an actual problem in separation science. Thus, such an unusual class of mathematical dependencies as recurrent relations was recommended for use in chemistry and, in particular, in chromatography. Recurrent relations allow revealing the existence of limiting values of both discrete and continuous properties. Recurrent equations are a special class of mathematical objects that are used most extensively for discrete functions of integer arguments. In solving the problem of estimating the gas chromatography retention parameters of a sorbate from the data obtained at other temperatures, several values in limited temperature intervals are considered as a rule.
