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. Pulse damper and mixer can be
bypassed for low flowrate applications or whenever a minimal transient
volume is desirable. Typical applications are high throughput methods with
fast gradients on high resolution 2.1 mm columns. 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 (optional) allows to form binary mixtures (isocratic or
gradient) from one of two solvents per channel. Active seal wash (optional) is
available for use with concentrated buffer solutions.
