    Definition in this chromatographic technique, the packing is nonpolar and the solvent is polar with respect to the sample. Retention is the result of the interaction of the nonpolar components of the solutes and the nonpolar stationary phase. Reference "Iowa State University, Office of Biotechnology http://www.protein.iastate.edu/hplc.html [7.10.2009]"

    Definition elution procedure used in liquid chromatography in which the mobile phase is significantly more polar then the stationary phase, e.g. a microporous silica-based material with chemically bonded alkyl chains Reference "IUPAC. Compendium of Chemical Terminology, 2nd ed. (the ""Gold Book""). Compiled by A. D. McNaught and A. Wilkinson. Blackwell Scientific Publications, Oxford (1997).

    Comment The term 'reverse phase' is an incorrect expression to be avoided

    Definition contrairement à la chromatographie de phase normale, en chromatographie à phase inverse la phase stationnaire est non polaire et la phase mobile modérément polaire. Les molécules qui sont plustôt non polaires en nature ont une rétention allongée et des molécules polaires s'éluent plus rapidement Reference "Infochroma ag. Chromatographie à phase inverse (RP) http://www.infoagil.ch/f/pnpi/pi.html [7.10.2009]"

    Definition reversed-phase high-performance liquid chromatography with a ternary mobile phase Reference "COM-Terminology Coordination, based on: P. Jandera. 'PREDICTIVE CALCULATION METHODS FOR OPTIMIZATION OF GRADIENT ELUTION USING BINARY AND TERNARY SOLVENT GRADIENTS' (8.2.2024) Journal of Chromatography 485 (1989) 113"
    Comment There are two types of ternary gradient chromatography defined by Jandera as ternary solvent-strength and combined selectivity-solvent-strength. In the case of the former, the ratio of the concentrations of two organic modifiers is kept constant; whilst the sum of the two concentrations is changed (i.e. the solvent-strength increases). In the latter case the ratio of the two organic modifiers and the sum of their concentrations changes simultaneously during gradient elution.
