The Agilent 1260 Infinity Binary LC - Product Description
System Components
1260 Infinity Binary Pump (G1312B)
The binary pump comprises two identical pumps integrated into one housing.
Binary gradients are created by high-pressure mixing. 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.
Principle of operation
The binary pump is based on a two-channel, dual-piston in-series design
which comprises all essential functions that a solvent delivery system has to
fulfill. Metering of solvent and delivery to the high-pressure side are
performed by two pump assemblies which can generate pressure up to
600 bar.
Each channel comprises a pump assembly including pump drive, pump head,
active inlet valve with replaceable cartridge, and outlet valve. The two
channels are fed into a low-volume mixing chamber which is connected via a
restriction capillary coil to a damping unit and a mixer. A pressure sensor
monitors the pump pressure. A purge valve with integrated PTFE frit is fitted
to the pump outlet for convenient priming of the pumping system.
