摘要： A continuous extraction system for countercurrent chromatography to achieve continuous solvent extraction, is disclosed wherein two immiscible solvents move in opposite directions through a rotating helical column (11). The coiled tube (11) has two pairs of flow connecting tubes, I u and I u to respectively feed and collect phase 1, and II u and II u to respectively feed and collect phase II. Elution of a desired phase takes place by use of a separation device at the head end which selects either the heavier or the lighter phase. This may consist of a suitably weighted suspended outlet tube (18) of Figure 2 in a rotating cylindrical outlet chamber (16) or may consist of a shunt "S" and settling chamber (40 of Figure 6) located outside the rotating part; the heavier phase may be removed from the bottom and the lighter phase may be removed from the top.
