    Area of Science:

    • Chromatography
    • Separation Science
    • Analytical Chemistry

    Background:

    • Traditional chromatography often relies on solid supports, which can lead to complications.
    • A need exists for separation techniques that avoid solid-phase interactions.

    Purpose of the Study:

    • To introduce and detail Countercurrent Chromatography (CCC) as a novel, versatile partition chromatography.
    • To highlight the advantages of CCC over traditional methods.

    Main Methods:

    • Utilizes the hydrodynamic behavior of two immiscible solvents within a rotating coiled tube.
    • Employs seal-free, flow-through centrifuge schemes for continuous elution.
    • Eliminates the need for solid supports, differentiating it from conventional chromatography.
