Abstract
Method of and appartus for liquid recirculation in at least substantially closed circuit which is particularly suitable for recycled liquid chromatography. The circulating liquid is brought into motion in the circuit inlet by working fluid supplied under pressure, e.g. from a pump, pressure gas cylinder, or the like. Circulating liquid approaching the end of the circuit beyond the circuit outlet is mechanically and at regular intervals repeatedly transported in the form of slugs into the beginning of the circuit in advance of the circuit inlet where these slugs are again forced into the circuit inlet by means of working fluid. The injection of one slug into the circuit inlet and the pushing of the following slug of equal volume out from the circuit outlet are carried out simultaneously.
