Agilent 1260 Infinity HPLC

The Agilent 1260 Infinity HPLC G1311C Quat Pump VL comprises an optional solvent cabinet,
a vacuum degasser and a four-channel gradient pump.
The four-channel gradient pump comprises a high-speed proportioning valve and a pump assembly.
It provides gradient generation by low pressure mixing.
A solvent cabinet provides enough space for four one-liter bottles.
An active seal wash can be purchased and installed by the user when the quaternary pump is used with concentrated buffer solutions.
The G1311C Quat Pump VL is based on a two-channel, dual-piston in-series design
which comprises all essential functions that a solvent delivery system must fulfill.
The design ensures virtually pulse free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled.
The variable stroke volume allows pulse-free solvent delivery and efficient mixing.

Metering of solvent and delivery to the high-pressure side are performed by one pump assembly which can generate pressure up to 400 bar.
Degassing of the solvents is done in a built-in vacuum degasser.
Solvent compositions are generated on the low-pressure side by a multi-channel gradient valve (MCGV), which is a high-speed proportioning valve.
The pump assembly includes a pump head with a passive inlet valve and an outlet valve.
A damping unit is connected between the two piston chambers.
A purge valve including a PTFE frit is fitted at the pump outlet for convenient priming of the pump head.
The Agilent 1260 Infinity HPLC G1311C Quat Pump VL is recommended for a wide range of research and routine applications as well as for method development.
