Introduction
Overview of the Hydraulic Path
the inner diameter of the pump head chamber allowing the solvent to fill the
gap inbetween. The first piston has a stroke volume in the range of 20 – 100 µL
depending on the flow rate. The microprocessor controls all flow rates in a
range of 1 µL/min – 10 mL/min. The inlet of the first pumping unit is
connected to the passive inlet valve.
The outlet of the first piston/chamber unit is connected through the outlet
valve and the damping unit to the inlet of the second piston/chamber unit. The
outlet of the purge valve assembly is then connected to the following
chromatographic system.
