Introduction to the Pump

The binary pump comprises two identical pumps integrated into one housing. Binary gradients are created by high-pressure mixing. A built-in degasser is available for applications that require best flow stability, especially at low flow rates, for maximum detector sensitivity. The pump is capable of delivering flow in the range of 0.1 – 5 mL/min against up to 600 bar. A solvent selection valve allows to form binary mixtures (isocratic or gradient). Active seal wash is available for up to three modifier solvents on channel B, while channel A is always the CO₂ delivering channel.
