WEBHow an HPLC pump works. Diagram of serial versus parallel pistons in an HPLC pump. Click image to enlarge. Most modern HPLC pumps have at least one pair of reciprocating pistons. One piston delivers the flow while the other aspirates the mobile phase at a programmed flow rate.
WEBThe quaternary pump is based on a two-channel, dual plunger in-series design which comprises all essential functions that a solvent delivery system has to fulfill.
WEBBoth the isocratic pump and quaternary pump are based on a two-channel, dual-piston in-series design which comprises all essential functions that a solvent delivery system has to fulfill.
WEBWhen leaving LC idle, pump a mobile phase with at least 5-10% of organic solvent. Observe the pressure limits of flow cells. Be careful when using detectors in series or fraction

How Does High Performance Liquid Chromatography (HPLC) Work?
WEBHigh-Performance Liquid Chromatography (HPLC) involves a solvent reservoir and a high-pressure pump to control the flow rate of the mobile phase. An injector introduces the sample into the flowing mobile phase, which carries it through the HPLC column containing stationary phase material for separation.
