The Thermo Scientific Quaternary Rapid Separation Pump combines flexible quaternary eluent proportioning with RSLC technology.
 
Use up to four solvents at pressures up to 15,000 psi (100 MPa) and flow rates up to 8 mL/min for fast routine applications and method development. The pump is ideal for ultrahigh-resolution separations using sub-3 μm and sub-2 μm particle size columns.

• Accurate, precise retention times thanks to the high flow-rate and proportioning precisions with quaternary gradient mixing.
• Exceptionally wide flow-pressure footprint, with flow rates from 100 µL/min to 8 mL/min and the ability to handle pressure up to 15,000 psi (103.4 MPa), with a flow accuracy of ±0.1%.
• Dionex's mixing concept perfectly balances gradient delay volume against mobile phase mixing efficiency. Mixing volume can be adapted to the application requirements in a matter of seconds.
• Reliable vacuum degassing with an internal four-channel micromembrane degasser.
• Active rear-seal wash for maximum seal lifetime, and reduced instrument down time.
