Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate. These two liquids, flowing in opposite directions, are brought into contact, mixed, and allowed to separate. According to the literature, the first attempt at chiral separation with CCC was by Prelog's group [1]. Countercurrent distribution (CCD, also spelled "co "counter current" distribution) is an analytical chemistry technique which was developed by Lyman C. Craig in the 1940s. Countercurrent chromatography (CCC) is a generic term covering all forms of liquid-liquid chromatography that use a support-free liquid stationary phase held in place by a simple centrifugal or complex centrifugal force field. They can achieve chiral separation through establishing a chiral environment by adding a chiral selector. Y.
