What is Chromatographic parameters: Characteristic parameters of solute retention – an insightful description of column properties about?
Previously introduced characteristic parameters of solute retention -the solute characteristic temperature ( T char ) and thermal constant ( θ ) in GC as well as the characteristic solvent composition ( φ char ) and the composition-constant ( ) in LC -are described herein from a single perspective. Unlike conventional thermodynamic parameters, e.g., entropy and enthalpy of solute evaporation from stationary phase in GC that do not have a direct chromatographic meaning, the characteristic parameters do. Thus, T char and φ char are the column temperature and the solvent composition in GC and LC, respectively, at which the solute retention factor ( k ) is equal to 1. Quantities θ and in GC and LC, respectively, are analogous to the time-constant in scientific and technical fields. Thus, e.g., is the increase in the solvent composition leading to e -fold reduction ( e ≈ 2.72) in k . Properties of characteristic parameters illustrating intuitive nature and simplicity of based on them concepts and equations are described.
