    摘要: A new mechanism for pulsation damping in a reciprocating diaphragm pump system is disclosed which is especially suitable for solvent delivery in modern high pressure liquid chromatography requiring a wide range of solvent flow rates and pressures. The disclosed damper has good overall performance over the full range of liquid chromatographic conditions, a dead volume independent of solvent pressure, and largely eliminates the necessity for continuously pumping the working oil of the diaphragm pump to a maximum operating pressure.

    摘要: A pumping apparatus (10), for delivering liquid at a high pressure at which compressibility of the liquid becomes noticeable, comprises a piston (20) adapted for reciprocation in a pump working chamber (30), wherein a movement of the piston (20) into a first direction (40) decreases a first volume (V1) in the pump working chamber (30) and increases a second volume (V2) in the pump working chamber (30), and a movement of the piston (20) into a second direction (50) opposite to the first direction (40) increases the first volume (V1) and decreases the second volume (V2). A coupling (70, 80, 90, 100) is provided for coupling the first volume (V1) with the second volume (V2) as long as a pressure (Psup) in the first volume (V1) exceeds a pressure in the second volume (V2). An outlet valve (120) is provided for coupling the second volume (V2) with an outlet (110) of the pumping apparatus (10) as long as a pressure in the second volume (V2) exceeds a pressure (Psys) at the outlet (110).

    摘要: The volumetric flow rate of a fluid is determined essentially independently of the properties of the fluid by guiding the volumetric fluid flow to be measured through an essentially linear flow resistor. An alternating flow of the fluid is superimposed on the volumetric fluid flow to be measured. Steady and alternating components of a pressure drop across the flow resistor are detected. A quantity representative of a property of the fluid is determined in response to the determined alternating component. The volumetric flow rate is calculated on the basis of the determined steady component and the quantity representing fluid property.
