Abstract
A diverter valve assembly includes a standard three-way valve and an upstream two-way valve and a further upstream eluant accumulator. When a new container is required for collection, the two-way valve stops the flow from the source. Since the source flow is continuous, the flow is directed into the accumulator pushing a spring loaded piston. When the new container is in position, the two-way valve opens and eluant flow from the source and the accumulator are directed to the new container. There is no flow to waste during the stoppage of flow.
