Stationary phases, chemically selective,

The tasks formulated above have determined the structure of the book, the first six chapters of which are devoted to accounts of the main chemical methods (preliminary processing of samples, kinetic methods, pyrolysis GC, determination of carbon skeleton, subtraction method, chemically selective stationary phases, elemental analysis). The last two chapters are devoted to the solution of two tasks that are most important in analytical chemistry nowadays the determination of impurities (Chapter 8) and the identification of components of complex mixtures by fimctional group analysis (Chapter... 

We just saw that, experimentally, EG and 1,2-DCA differentially migrate through a stationary phase when introduced into a suitable mobile phase and that chromatography arises when this mobile phase is allowed to pass through a chemically selective stationary phase. It is not sufficient to merely state that EG is retained longer than 1,2-DCA. It is more accurate to state that EG partitions to a greater extent into the stationary phase than does...
