Overview of the Quaternary Pump

The Agilent 1290 Infinity Quaternary Pump has a built-in 4-channel vacuum
degasser for best flow stability, especially at low flow rates and maximum
detector sensitivity. It uses a multi-channel gradient valve (MCGV) for
formation of quaternary gradients at low pressure. The low-pressure Inlet
Weaver based on patented Agilent microfluidic technology ensures highest
mixing performance and lowest mixing noise. The pump head offers a high
power range with a maximum pressure of 1200 bar and a maximum flow rate
of 5 mL/min. The Multi Purpose Valve can be used for automatic purging,
using an optional Jet Weaver high-performance mixer, automatic back-flushing
of the optional inline filter or for diagnostic.
The Agilent 1290 Infinity Quaternary Pump is suitable for a wide range of
columns and HPLC und UHPLC applications starting from typical
250 x 4.6 mm HPLC columns going down to high resolution 50 x 2.1 mm
UHPLC columns and can be used in a flow range between 0.05 – 5 mL/min.
The active seal wash function can be used with concentrated buffer solutions.
