Analysis of Chromatographic Parameters in the Systems with Ternary Mobile Phases. II. Two Polar Solvents in Mobile Phase

Abstract

The experimental data are presented on Gibbs triangles in the form of isolines. The effect of change of the type of two polar mobile phase components on the chromatographic parameters of model substances has been investigated. The presence of alcohol in ternary mobile phase leads to formation double or “closed” R_F isolines on Gibbs triangles. Such presentation of the experimental data allowed to complex analysis of the chromatographic process in systems with ternary mobile phase. The measurements were made by adsorption thin layer chromatography on silica gel at temperature 293 K.
