Abstract
The present invention relates to a preparative chromatography system () and a chromatography process () adapted to repetitive cycling of chromatography volumes. The system () comprises at least two upstream pumps () and separate flow paths () from process liquid sources to the chromatography device (). The system () is arranged to prime one flow path () with one process liquid while providing another process liquid to the chromatography device and thereby minimizing the hold-up volume of the system ().
