Title: CHROMATOGRAPHIC SEPARATOR
Abstract:
A chromatographic separator which circulates a raw material liquid having at least two components and an eluate through a circulating path (16) consisting of endlessly connected columns (14) to separate the raw material liquid into two components. Switching between switching valves (23, 33) allows pumps (20, 30) to be used both for liquid circulation through the circulating path (16) and for liquids flow-in from respective storage tanks (25, 35). On-off valves are used for draining valves (41, 51) for respective liquids to lower the pressure specifications of the circulating path (16).
