    Chromatography
    A substance is passed between a stationary phase (solid or liquid) and a mobile phase (liquid or gas) flowing in contact with it, and the difference in affinity for both phases is used to generate the target substance. How to separate components.
    When the mobile phase is liquid, it is called liquid chromatography, and when it is gas, it is called gas chromatography.
