ABSTRACT:
Apparatus for simultaneously supplying solvent to a plurality of chromatography columns using a plurality of pumps. Each pump has a chamber with a movable solvent piston therein and inflow and outflow valves. The outflow valve of each pump is connected to a respective chromatography column. The solvent pistons are simultaneously moved in one direction to pull solvent into the respective chambers until all pistons have achieved an adjustable stop position corresponding to a desired delivery volume. The solvent pistons are then simultaneously moved in the opposite direction to deliver solvent to the respective columns until all pistons have delivered the desired delivery volumes. The solvent pistons are driven by a common pneumatic or hydraulic system.
