Key terms

  • Stationary Phase

    The phase in chromatography that remains fixed in place and interacts with the analytes.

  • Mobile Phase

    The phase in chromatography that moves through the stationary phase and carries the analytes.

  • Chromatography

    A technique used to separate mixtures into their individual components based on their movement through a stationary phase.

  • Solvent front

    The furthest point reached by the solvent in chromatography, used as a reference for calculating Rf values.

  • Chromatography

    A technique used to separate and analyze components in a mixture based on their different interactions with a stationary and a mobile phase.

  • Thin-Layer Chromatography (TLC)

    A chromatography technique where a thin layer of stationary phase is coated on a flat surface, allowing for the separation of small quantities of substances.

  • Chromatography

    A technique used to separate and analyze components in a mixture based on their different interactions with a stationary phase and a mobile phase.

  • Retention Factor (Rf)

    A numerical value that represents the ratio of the distance traveled by a compound to the distance traveled by the solvent front in chromatography.
