Automated multi-step chromatography purification system (400) comprising a system controller (401), a capture flow path (410) with at least one pump (425) and two or more capture columns (412a, 412b, 412c), an elution flow path (415, 420) with purification columns (417, 422a, 422b) for subsequent purification, and a valve arrangement with two or more valves (407, 411a, 411b, 421a, 421b), said valves being controlled for selective connection of said capture columns to the capture flow path and the elution flow path respectively such that both flow paths may be operated simultaneously and in parallel. |
