Abstract: Disclosed is a chromatography system (100) comprising: plural modules (1-25) including at least one pump and a column valve unit (8) connectable to plural chromatography columns; and a controller (600), the controller being operable to control the or each pump and the column valve to perform different chromatographic processes, including chromatography employing just one column, as well as chromatography employing just one column, as well as chromatography employing two or more columns by selective valve opening in said unit. The system includes a housing (110) into which the plural modules (1-25) are interchangeably mountable in apertures of one generally vertical face of housing, the modules are adapted for selective fluidic interconnection by tubing substantially at said one face such that in use the modules and tubing occupy a generally vertically extending volume to minimize the footprint of the system.

Abstract: The present invention relates to a valve unit for a chromatography apparatus, the valve unit comprising a fluid inlet configured to receive an input fluid, a fluid outlet configured to provide an output fluid, a first pair of fluid ports configured to be coupled to a first column, a second pair of fluid ports configured to be coupled to a second column, a coupling valve assembly configured to direct fluid between a selection of the fluid inlet, the fluid outlet, the first pair of fluid ports and the second pair of fluid ports in response to one or more control signals, wherein the coupling valve assembly is configured to direct fluid using a selection of membrane valves coupled by fluid channels comprised in a body of the coupling valve assembly. The invention further relates to a chromatography apparatus comprising the valve unit and a membrane valve comprised in the valve unit.
