Agilent 1290 Infinity G4204A 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 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. Active seal wash is optionally available for use with concentrated buffer solutions.
